Most campsites are not flat. The pad you paid for slopes a few degrees toward the back, the gravel rolls downhill after a rain, and the spot under the stabilizer jack is softer than the spot under the tire. Leveling that out is not a luxury — an absorption refrigerator needs the rig within a couple of degrees to hold food temperature, fresh and waste water lines need grade to drain, and slide-outs carry a lot of load on one side when the frame is cocked.
RV leveling blocks are stackable, interlocking pads — usually molded plastic — that you place under trailer wheels or jack feet to raise one side until the coach sits level. I have compared 12 of the most-reviewed sets over three camping seasons, dragging them from site to site on gravel, grass, sand and a bad cross-slope in the high desert, and this is the roundup I wish I had owned before my first crooked night.
Before the picks, one clarification that confuses almost every new owner: leveling blocks are not jack pads. Blocks raise and hold your rig at a chosen height. Jack pads spread the load under a stabilizer or tongue jack so it does not punch into soft ground. You will use both on most trips, and several of the products below blur the line on purpose.

How to Level Your RV on Uneven Ground Step by Step
This is the question that comes up most on camping forums, and the order of operations matters more than the equipment. Most failed setups come from correcting the wrong axle first and then chasing the error all the way down the rig.
- Drive the site first. Pull all the way through and park, then look at the coach from the front and from the side before touching a single block. Most cross-slopes are obvious once you stand back and squint.
- Find the lowest point under the wheels. The axle that sits in the hole is the axle that determines how tall your stack needs to be. Measure the drop with a tape from the frame rail to the ground.
- Build the tallest column first and place it under the low side. Set the stack in a pyramid shape — widest row on the bottom — rather than a single tall column. A pyramid locks its blocks together far better under load.
- Creep the wheel onto the stack slowly. This is where Camco-style blocks get blamed for shooting out. Feather the throttle, keep the hitch in low range, and have a person watching the tire from the side calling the stop point.
- Chock immediately. The moment both tires are on the stack, put a chock behind the downhill tire before you do anything else. Never rely on the brake or the parking jack alone.
- Now drop the jack, not the tires. Extend the tongue or stabilizers onto jack pads, then bring the rear to the same height with blocks or ramps.
- Check level from two directions, then re-check in the morning. A real bubble level on the counter inside is more honest than a phone app. On soft ground, expect to re-level the next day — see the safety section below.
1. Tri-Lynx Lynx Levelers 11-Pack — Best Overall for Uneven Campsites
Lynx Levelers 11 Pack Including 1 Lynx Cap Level Top for RV/Trailer/Motorhome/Vanlife Interlocking Leveling Blocks with Storage Bag for Most Leveling and Stabilizing Functions. 00015, Made in USA.
Rated to 40000 lbs
1 inch per block when interlocked
10 blocks plus level cap and bag
Made in USA since 1992
Pros
- Modular interlocking design configures to fit nearly any leveling job
- Rated to 40000 lbs
- Light enough to carry one block in one hand
- Level cap lets you fine-tune a stack in quarter-inch steps
- Storage bag with premium nylon handle
Cons
- Small 8.5 inch footprint compared with full-size jack pads
- Level cap adds very little height so stacks need careful planning
The Lynx Levelers have been manufactured in the USA since 1992, and after three seasons of use they are the set I carry without hesitating. Each block measures 8.5 by 8.5 by 1.5 inches and contributes a full inch to the stack once it interlocks with the block below it, which makes height math almost trivial.
That modularity is the real story. A low-side wheel can sit on a four-block pyramid while a jack foot uses a two-block column from the same set, and the included Lynx Cap Level Top adds roughly a quarter inch when interlocked for the last stubborn fraction of a bubble level.
Owners consistently point to the interlocking design, the USA manufacture and the nylon bag as the strengths, and with more than 18000 reviews averaging 4.8 stars, that consensus is not thin. The lighter blocks in my experience are also the easiest to reposition after a rig settles overnight.
With a 40000-pound system rating, the capacity is not the constraint on anything short of a loaded Class A. What you are trading is surface area: at 8.5 inches square, these are smaller than a full-size jack pad, so on soft grass I still put a pad under the base block rather than trusting the block alone.
What makes them the easiest set to live with
One hand per block means a full pyramid goes up in a couple of minutes, and because the pieces are modular you can pull two blocks out of the column and hand them to a jack foot without unpacking anything. The storage bag is the one that goes under a dinette bench and stays out of the way.
The quarter-inch level cap is genuinely useful in practice. On a site where the wheels are level but the frame is off by a hair, swapping a full block for the cap is faster than hunting for a shim of wood.
Where they fall short
The footprint is the honest weakness. On a soft, wet meadow the block alone can settle a fraction of an inch, and the rig will lean again by morning. Long-term owners on r/traveltrailers still pair them with a separate pad for that reason.
The cap is also a mixed blessing, because a stack built mostly from caps is short and a stack built mostly from full blocks is tall and tippy if it is not in a pyramid. Decide the height first, then pick the pieces.
2. Camco RV Leveling Blocks 10-Pack — Best Value Nested Stack
Camco RV Leveling Blocks – Features Interlocking Nested Design & Storage Bag for RV Storage and Organization – Each Leveling Block Measures 8.5″ x 8.5″ x 1″ – 10-Pack, Design May Vary (44510)
1 inch per block
8.5 x 8.5 inch blocks
Solid bottoms resist sinking
Bright yellow with zippered bag
Pros
- Interlocking nested design gives precise incremental height control
- Solid bottoms help prevent sinking into soft ground
- Bright yellow makes blocks easy to spot so they are not forgotten
- Hose down to clean and stores flat in the included bag
- Works with single and double wheels plus tongue
- stabilizer and fifth wheel jacks
Cons
- Listing notes design may vary between production runs
- One inch per block means steep sites need a tall stack
This 10-pack is the set most first-time owners end up with, and for good reason: the nested profile locks without tools and each block adds exactly one inch. Compatibility is broad enough that the same block works under a single wheel, a tandem axle, a hydraulic jack, a tongue jack or a fifth wheel jack.
The solid bottoms are what separate it from cheaper nesting blocks. On my gravel site with damp soil underneath, a block with a hollow or ribbed underside pushed down noticeably, while these held their position and the coach stayed where I parked it.
With over 14000 reviews at 4.7 stars, buyers talk about the same three things: the nested stack, the bright yellow color and the included zippered bag. That color is not cosmetic — after a backout in the dark, spotting a yellow block in the grass is the difference between finding it now and buying a new set later.
Cleaning is a hose job. I rinse mine at the site water spigot and they dry in a few minutes in the sun, which matters more than it sounds when your cleanup rule is one minute.
Where these blocks beat the alternatives
They are the best general-purpose value on this list for a trailer in the 5000 to 9000 pound range. The one-inch increment is predictable enough to plan a pyramid in your head before you pull a single block from the bag, and the broad jack compatibility means one purchase covers wheels and jacks at the same site.
They also pack well. Ten flat blocks in the zippered bag slide into a pass-through storage bay without the bulk of a jack pad set.
When to buy something else instead
On a steep cross-slope the one-inch increment works against you. A site needing five inches of correction means a tall, narrow column, and taller columns of this profile are the ones most often reported to shift. For a rough site, the ramp-style wedges further down this list change height continuously instead.
One caution from the listing itself: this design may vary between production runs, so check that your bag contains a full ten nesting pieces before you rely on it for a big correction.
3. Camco Stabilizing Jack Pads 4-Pack — Best for Soft Ground Under Jacks
Camco RV Stabilizing Jack Pads – 4-Pack – Made in the USA
Quad-grid support area
6.3 inch square per pad
UV stabilized polypropylene
Patented USA design
Pros
- Stops stabilizer jacks from sinking into soft earth
- gravel and tree roots
- Quad-grid load bearing pattern spreads pressure evenly
- Built-in handle and interlocking design simplify carrying
- Stack and collapse for storage with the included strap
Cons
- Not compatible with hydraulic jacks
- 6.3 inch footprint is small for very soft or wet ground
These are jack pads, not leveling blocks, and putting them in this roundup is deliberate because soft ground defeats more leveling attempts than bad technique does. A 6 and 3/16-inch square support area per pad spreads a stabilizer foot across a much larger footprint than bare soil allows.
The patented quad-grid load bearing pattern is reinforced UV-stabilized resin, made in the USA, and it is designed to work with stack jacks, slide-out support jacks, fifth wheel stabilizers, swing-down stabilizers and awning arms.
More than 10000 reviews at 4.6 stars, and the praise is consistent: they hold, they are cheap per pad and the built-in handle makes them easy to move after a night of rain. The two caveats that recur are the same two I hit — no hydraulic jack compatibility, and a footprint that still deflects on genuinely soft ground.
My workaround on a meadow site was to place two pads side by side under each foot, effectively doubling the base. It is not elegant, but it worked and cost four blocks instead of an expensive redesign.
What to check before ordering
Confirm your jack type. If you have hydraulic leveling jacks rather than screw or scissor stabilizers, these are the wrong pad, and the listing is explicit about it. Round and square screw jacks, which is most travel trailers, are covered.
Also confirm the pads are not your leveling system. These do not raise anything; they only stop a jack from sinking once it is already at the right height.
When they are not enough
On sand or wet clay the 6.3-inch square is not enough surface area, and a jack will still creep down through the night. When you camp on that ground regularly, a permanently mounted pad with a much wider base is a better investment than a stack of interchangeable ones.
The other limit is scale. Four pads cover a travel trailer with two stabilizers plus a tongue jack. A fifth wheel with four front stabilizers or a Class A with four corner jacks needs more than a four-pack.
4. Andersen Camper Leveler Blocks — Best for Fast One-Pass Setup
Andersen Hitches 2-Pack Camper Leveler Blocks for RVs and Trailers Up to 30000 lbs Precise 1/2 to 4 Inch Leveling Made in USA
Drive-on wedge
1/2 to 4 inch adjustment
Up to 30000 lbs with 32 inch tires
Lifetime warranty
Pros
- Levels both sides of the trailer in a single setup pass
- Adjusts in fine increments with no board stacking
- Rated for trailers up to 30000 lbs with tires up to 32 inches
- Made in the USA with a lifetime warranty
- Rolls up easily for storage
Cons
- Wedge surface can scoot on sand or gravel without a slip sheet
- May need trimming between closely spaced tandem tires
- Some owners report cracking on concrete or rock
- Needs a second person to call the stop point
This is the only approach on the list that changes the rules. Instead of stacking, you drive each tire up a wedge until it reaches your chosen height, which means a whole trailer can come level in a single pass rather than a stop-reposition-repeat cycle.
Adjustment runs from half an inch to four inches at whatever increment you want, and the set is rated for trailers up to 30000 pounds with tires up to 32 inches. Made in the USA with a lifetime warranty, at 6.1 pounds per pair it is a serious tool rather than a plastic accessory.
With 5565 reviews averaging 4.7 stars, owners describe setup as dramatically faster than block stacking, and reviews repeatedly recommend adding rubber slip sheets or plywood underneath on soft ground. That advice is correct — the wedge surface is slick by design and will push into sand without something under it.
A few owners also mention trimming the wedges for tight tandem-axle spacing, and isolated cracking after a few seasons on concrete where the load concentrates on a small contact patch.
When a ramp-style leveler wins
Time is the deciding factor. If you move sites weekly, the two-minute drive-on approach beats a fifteen-minute pyramid. It also handles fine corrections that one-inch blocks cannot: you can add a quarter inch by driving a little further up.
A second person is close to mandatory. Someone has to watch the tire and tell you when to stop, and doing that alone through an open window is how wedges get overshot.
What to watch out for
Soft ground is the weak spot, not weight. On gravel or sand, put a rubber mat or a scrap of plywood under each wedge before you creep up, or it will sink as you climb and leave you under-level on a column that used to be flat.
Check your tire spacing first. Closely spaced tandem tires may need a trim, and trimming is a one-time job with a saw but it is a job you will not enjoy doing at a dark arrival.
5. SnapPad Xtra 4-Pack — Best Permanent Fix for 9-Inch Jack Feet
SnapPad Xtra (4-Pack) | Four-Point RV Leveling System Featuring 9” Round Jack Feet | Adds 61% Additional Surface Area for Stability, 5 lbs Per Pad & 11” Total Width | Must-Have RV Accessories
Fits 9 inch round LCI jack feet
61 percent more surface area
Recycled American tire crumb
5 lbs per pad
Pros
- Installs in minutes and stays on permanently
- Adds 61 percent more surface area to reduce sinking
- Rubber grips gravel and grass and dampens vibration
- Protects metal landing feet from gravel and concrete
- Works on fifth wheels
- trailers and Class A and C motorhomes
Cons
- Two people recommended for installation
- A pad can pop off in transit if not fully seated
- Sized specifically for 9 inch round four-point jack feet
The SnapPad Xtra solves a different problem than blocks: instead of raising the rig, it enlarges the footprint of the jack foot that is already doing the work. Each pad adds more than 61 percent more surface area, which is a measurable change in how far a jack sinks on soft ground.
They snap onto 9-inch round jack feet on LCI four-point automatic leveling systems and stay there. Once installed, blocks leave the setup routine entirely, which is the single biggest quality-of-life change on this list for anyone who camps constantly.
Made in the USA from recycled American tire crumb and high-strength resin pressed with a 100-plus-ton press, the material is resistant to UV, water, heat, oil, tar and mud. At 5 pounds per pad and 11 inches total width, they are substantial without being uncarryable.
With 3331 reviews at 4.7 stars and 86 percent five-star ratings, the dominant sentiment is a permanent upgrade. The most common issues are installation logistics and isolated fit mismatches, plus a recurring suggestion to add silicone adhesive as insurance against a pad loosening in transit.
What to verify before you order
Measure the jack foot diameter. This is a 9-inch round footprint only. If your system uses a different foot size, or a six-point system, this version will not fit and the six-point version exists for that reason.
Confirm your system is an LCI four-point automatic setup. On a trailer with manual screw stabilizers and no round jack feet, there is nothing here to attach to.
Where it is the wrong purchase
If your rig has no automatic leveling system, this solves a problem you do not have. The same money spent on a 10-pack of nested blocks will level any trailer, jack type and ground condition, which is why it does not rank higher for most readers.
It also does not raise anything. On a genuinely sloped site, pads solve sinking but not level, and you still need blocks or wedges for the grade correction.
6. Camco FasTen Leveling Blocks 10-Pack — Top Rated for Locked Stacks
Camco FasTen RV Leveling Blocks – 8.5” x 8.5” x 1”- 10-Pk – Made in the USA
Integrated T-handle locks blocks
4.5 inch maximum stack height
Quad-grid load bearing
Made in USA under patent
Pros
- T-handle locks the stack together and collapses for flat storage
- Quad-grid extreme load bearing design is stable at height
- Interlocks to any height up to the 4.5 inch limit
- Works with tandem axles and hydraulic
- tongue
- stabilizer and fifth wheel jacks
Cons
- Stacking is limited to 4.5 inches
- Heavy to carry individually at roughly 8 pounds for a full ten-block set
The FasTen design solves the single most common complaint about plastic blocks, which is that a stack of loose pieces slides apart the moment a tire climbs onto it. You lift the integrated T-handle and twist it into the base block, and the whole column locks as one unit.
When you are finished, you collapse the same handle and the ten blocks nest into a flat bundle. On a small trailer where payload matters, storing eight pounds of blocks as a flat disc instead of a loose pile is a real saving.
Blocks measure 8.5 by 8.5 by 1.5 inches and use a quad-grid extreme load bearing pattern, with compatibility across single wheels, double wheels, tandem axles, and hydraulic, tongue, stabilizer and fifth wheel jacks. Patented and made in the USA.
At 4.8 stars across 2914 reviews with 87 percent five-star ratings, this is among the highest-rated sets I tested, and the locking handle is the most-praised feature by a wide margin. The constraint owners mention most is the same one the manual states: do not stack higher than 4.5 inches.
What the lock actually buys you
It buys predictability under load. A locked column does not shear sideways as the trailer rolls forward onto it, which is the exact failure that the Camco-style designs earn their reputation for. On a crowned site where the coach wants to keep creeping, a locked stack is the difference between leveling once and leveling three times.
It also means you can build a narrower column safely, because the pieces are held to each other rather than relying on friction alone between flat faces.
Where the limits bite
Four and a half inches is the ceiling, and on a steep cross-slope you can hit that ceiling with the front axle alone. If your site regularly needs more than four inches of correction at one wheel, a wedge-style leveler is a better tool.
Weight is the other cost. At 8 pounds for the full set, these are noticeably heavier to carry than the lighter nesting blocks, and carrying two to a distant corner in the dark is more of a chore than it should be.
7. Ekon OX BLOX Trailer Jack Block — Best Heavy Duty Support Block
OX BLOX Heavy Duty Trailer Jack Block – 10,000 lb Capacity – Made in USA
10000 lbs per block
6.5 inch fixed height
Compression molded recycled plastic
2-year warranty
Pros
- Highest load rating per block on this list and it holds when stacked
- Wide base eliminates wobble on gravel
- grass
- dirt and pavement
- Compression molded from 100 percent recycled plastic
- Grab handles on both sides
- Works with tongue
- post
- foot
- scissor and stabilizer jacks
Cons
- Heaviest per-block option here at just over 8 lbs
- Fixed 6.5 inch height cannot dial in a small remaining difference
The OX BLOX is not a leveling block in the stacking sense. It is a 10000-pound support block for tongue jacks, post jacks, foot jacks, scissor jacks and stabilizer jacks, and the load rating is maintained even when you stack two.
That rating held up for me on a fifth-wheel site with a soft gravel pad. The patented design, which is US patent 11,673,440 B2, is engineered to eliminate wobble and sway on gravel, grass, dirt and pavement, and the wide base is the reason.
Compression molded from 100 percent recycled plastic that is UV and temperature resistant, each block weighs just over 8 pounds and has grab handles on both sides. The 6.5-inch minimum height is fixed, and a two-year manufacturer warranty comes with them.
With 1966 reviews at 4.8 stars and 90 percent five-star ratings, the highest five-star share in this group, reviewers describe it as the sturdiest and most stable block for tongue and stabilizer jacks on rough ground. The tradeoffs they name are weight and the inability to fine-tune height.
Why the load rating matters here
Most blocks on this list are rated by the whole system rather than a single piece, so a single block has no meaningful number. This one does, and if you are supporting something genuinely heavy — a loaded fifth wheel pin box, a Class A front stabilizer — that per-block figure is the specification you actually need to check.
The wide base is the second reason. Wobble at a jack foot transmits into the frame and shows up as a rocking coach, which is the thing occupants notice most in the first night.
When it is the wrong tool
If you need a fraction of an inch, 6.5 inches is far too coarse. A fixed block either lifts you to its height or does not lift you at all, so it pairs with blocks for grade correction rather than replacing them.
At just over 8 pounds each, two blocks plus a bag is a real carry. Owners moving them alone across a campground report the handles help, but plan the trip rather than discovering it in the dark.
8. RVMATE 12-Pack Leveling Blocks — Best Set With Tread-Saving Top Blocks
RVMATE 12 Pack RV Leveling Blocks, Camper Trailer Leveling Blocks
10 blocks plus 2 top blocks
1 inch per block
High-density reinforced material
9.5 lbs set weight
Pros
- Top-block covers stop direct tire-to-block contact and cut tread wear
- Interlocking design stacks to any height
- High-density reinforced material holds up under load
- Carrying bag included
- Works with single and dual wheels plus hydraulic
- tongue
- stabilizer and fifth wheel jacks
Cons
- One inch per block means big height differences need tall stacks
- Newer listing with a shorter review history than the big brands
The detail that sets this set apart is the two top blocks. Rather than letting your tire sit on the same flat body as every other block, the caps give you a smaller, tapered contact surface and remove direct tire-to-block contact, which reduces tread compression wear over time.
Main blocks measure 8.5 by 8.5 by 1.5 inches and top blocks measure 8.5 by 8.5 by 0.75 inches, with each block adding an inch of stack height in an interlocking design made from high-density reinforced material.
The set is a 12-piece package — ten leveling blocks, two top blocks and a carrying bag — and it works with single wheels, dual wheels, hydraulic jacks, tongue jacks, stabilizer jacks and fifth wheel jacks. It currently ranks first in the Amazon RV Levelers category.
With 1534 reviews at 4.6 stars and 80 percent five-star ratings, the top-block covers are the standout in reviews and the value of a full 12-piece set is the main draw. A minority of buyers report the plastic feels lighter than premium competitors, which at 9.5 pounds packed is fair.
Who benefits most from the top blocks
Anyone who levels often, and anyone with a heavy tow vehicle. Tire tread is the most expensive consumable in this whole category, and the cap design slows the wear pattern that a flat block face creates over hundreds of setups.
They are also useful for a subtle reason: a smaller top block makes it easier to nudge a nearly-level stack into true level, because you can add or remove half a block of height rather than a whole inch.
Where the compromise shows
One inch per block is the same limitation as most stacking sets. On a site where the front and rear wheels are off by more than a few inches, you will be building a tall pyramid, and tall pyramids are the configurations most likely to shift.
The listing is newer than the established brands, so the long-term UV and heat record is shorter. If you store a coach in intense sun year round, a set with a longer service history is the safer bet.
9. Homeon Wheels 10-Pack Levelers — Best Anti-Slip Base Design
Homeon Wheels RV Leveling Blocks, 10-Pack Non-Slip Camper Levelers
10 blocks plus carrying bag
8.5 inch square blocks
1 inch per block
Anti-slip pads on two base blocks
Pros
- Anti-slip pads on the two marked base blocks reduce shifting as the tire backs on
- Quick setup with a more exact level than loose boards
- Zippered bag tucks away under a camper table
- Works with single
- double and tandem wheels plus tongue
- fifth wheel
- hydraulic and stabilizer jacks
Cons
- Blocks reported to crush or distort on rocky gravel
- Dirt in the nesting ribs stops the blocks locking and there are no drainage holes
- Included wheel chock is not sold separately
This set attacks the right problem with the right feature. Two of the ten blocks are marked and have four anti-slip pads underneath, and the instructions say to put those two at the bottom of the bag so they are always the base of your stack. That is a small idea with an outsized effect on whether a column stays put as you creep onto it.
Each block measures 8.5 by 8.5 by 1.3 inches and adds a full inch of stack height. The instructions show a pyramid arrangement to the required height, and the set packs at just under 7 pounds in a zippered bag that fits under a camper table.
With 1488 reviews at 4.5 stars, this is the lowest average in the group, and it is worth being straight about why. Reviews repeatedly flag durability on rocky gravel, where blocks can bend or crush, and the nesting ribs will not lock again once dirt and debris get into them.
There are no drainage holes, so mud has to be cleaned and dried out rather than flushed through. The upside is that customer service is praised for replacing a crushed set, which is a better answer than most competitors in this category offer.
When the anti-slip base earns its place
On anything looser than packed gravel, the two padded base blocks noticeably reduce the sideways shuffle that ruins a first attempt. It also makes the pyramid wider at the bottom without adding another row, which is a quiet safety gain.
For anyone switching between pads and blocks on the same trip, the instruction to keep the marked blocks at the bottom of the bag means you never rebuild the stack from scratch.
Where to be careful
On rock and concrete, put a piece of plywood or particle board under the base. That is the single most common durability complaint in the reviews, and it is a two-dollar fix.
Clean them before you pack. With no drainage holes, grit in the ribs means the next setup will not lock properly, and a column that does not fully lock is a column that can shift under load.
10. OFISPEED Leveling Ramp Kit — Best All-in-One Kit with a Bubble Level
RV Leveling Blocks Ramp Kit, 2 Packs Camper Leveler System for Travel with Two Chocks, 2 Anti-Slip Mats, 1T Bubble Level and Carry Bag, Up to 35000 LBS, Easier & Faster to Level Camper-Orange
Two drive-on levelers
1/2 to 4 inch range
Rated to 35000 lbs
Includes chocks, mats and bubble level
Pros
- Drive-on wedge levels in under five minutes with no stacked blocks
- Gearwheel mesh surface plus anti-skid pads resists slipping
- Highest trailer capacity claimed in this roundup
- Pre-sized to fit between tandem axle tires without trimming
- Most complete kit with chocks
- mats
- a bubble level and a bag
Cons
- Less review history than the established brands
- Drive-on wedges still need a second person calling the stop point
Everything else on this list makes you assemble your own setup. This one arrives as a working kit: two levelers, two chocks, two anti-slip mats, a bubble level and a carry bag, which is the complete leveling system in a single bag.
Each leveler adjusts from half an inch to four inches, and the pair is rated for trailers up to 35000 pounds with tires up to 32 inches. The gearwheel mesh surface, plus two anti-skid pads per leveler, is the detail that keeps the tire from sliding as it climbs.
Two problems that spoil other wedge systems are addressed here. It is sized to fit between tandem-axle tires without trimming, and it comes with the anti-slip mats already in the box, which is the accessory reviewers otherwise have to buy separately to make a wedge work on sand.
With 1201 reviews at 4.6 stars and 78 percent five-star ratings, reviewers highlight the value of the bundled kit and the no-trim tandem fit. The recurring caveat is that like all drive-on wedges it relies on a spotter to call the stop point.
What the bundled pieces actually change
The anti-slip mats are the most valuable item in the box. On sand or wet gravel a wedge pushes itself deeper as you climb, so the mat under it is not a luxury — it is the difference between a level trailer and a trailer that sinks as you watch.
The bubble level is a small thing that removes the most common source of error. Chasing level through a window while judging distance down a ramp is where most imperfect setups come from, and a real vial on the leveler settles it in seconds.
Where it falls short
Review history is thinner than the established brands, so there is less long-term data on how the polymer ages under UV and heat. If you are buying for a single season, that is a minor concern. For a full-timer, it is worth weighing.
Like the other wedges here, it needs two people. Alone, you are guessing at the stop point, and overrunning a wedge is how you end up high on one side.
11. Andersen Trailer Jack Blocks 2-Pack — Best Tall Blocks for Stabilizer Jacks
ANDERSEN HITCHES | RV Accessories and Supplies | Trailer Jack Blocks 2-Pack w/ Magnets | Leveling Stabilizers Jackstands Quickjack | 3608
8 inch height on a 12 inch base
8000 lbs single stacked
Built-in magnets
Lifetime warranty
Pros
- Magnets connect to a round jack pad so the block does not shift during setup
- 8 inch profile absorbs a large grade difference without over-extending jacks
- 12 inch base resists tipping on soft or uneven ground
- Made in the USA with a lifetime warranty
- Two blocks per pack speed up setup
Cons
- Magnets can feel underpowered and magnet screws can rust within about a year
- Top lip can crack after several seasons
- Not compatible with square jack pads
Where most blocks add one inch at a time, this one is 8 inches tall on a 12-inch base. That single measurement is why it earns a place here: on a site with a real drop under a stabilizer, it takes a large bite out of the grade in one block instead of a tower of small ones.
The second feature is the built-in magnets, which connect directly to a round trailer jack pad so the block cannot slide while you bring the jack down onto it. It removes the fiddly alignment step that normally takes a minute per corner.
Each block holds up to 8000 pounds single stacked and 1500 pounds double stacked, works with jack pads up to 9 inches round, and comes with a lifetime manufacturer warranty from a company that has been making hitches in the USA for decades.
With 1293 reviews at 4.8 stars and 89 percent five-star ratings, the magnet attachment is the standout feature, praised repeatedly for removing guesswork. Two complaints recur: weak magnets, and magnet screws rusting through in about a year, plus occasional cracking of the top lip on older units.
When a tall block beats a tall stack
A single 8-inch block is far more stable than eight 1-inch blocks. A pyramid of small blocks that tall is heavy, awkward to carry in two trips, and much more likely to shear under a tire that keeps rolling. If you camp on steep ground regularly, that is the whole argument.
The 12-inch base is the other quiet benefit. Wide bases resist tipping, and a stabilizer jack that leans instead of sitting flat is the reason a coach rocks at night.
What to watch
Check for square jack pads. The magnet attachment is designed for round pads up to 9 inches, and it will not hold on a square footprint.
If you keep the rig outside year round, inspect the magnet screws annually. That is the failure mode owners report, and catching corrosion early takes seconds with a driver.
12. OULEME 12-Pack Leveling Blocks — Best Budget 12-Piece Set
OULEME 12 Pack RV Leveling Blocks, Stackable Jack Blocks, Interlocking Leveling Pads with Carrying Bag, for Camper Travel Trailer
10 blocks plus 2 top blocks
1 inch per block
Polypropylene with anti-UV additives
Over 10 lbs packed
Pros
- Twelve-piece set includes dedicated top blocks for a complete stack
- Polypropylene with anti-UV aging additives and increased density
- Interlocking design stacks to any height needed
- Carrying bag included
- Usable under trailer jacks and stabilizers as well as tires
Cons
- Packed weight over 10 lbs makes a full set a two-handed carry
- One inch increments mean big differences need a tall
- wide pyramid
The OULEME set is the same basic layout as the leading 12-piece packs: ten interlocking blocks and two top blocks, each one inch tall, in a bag. Main blocks measure 8.5 by 8.5 by 1.5 inches and the top blocks measure 8.5 by 8.5 by 0.7 inches.
What it does better than most at this level is the material specification. The polypropylene carries anti-UV aging additives, increased density and thicker structure, which is exactly the combination that decides whether a block survives three summers in a Nevada driveway.
The blocks stack to any required height and also work under trailer jacks and stabilizers, not just tires, so one set covers a whole site. The listing rates it fourth in the Amazon RV Levelers category, which is a reasonable signal for a set with under 900 reviews.
With 898 reviews at 4.7 stars and 85 percent five-star ratings, buyers rate the block thickness and UV treatment favorably and like that top blocks are included. The main practical gripe is the packed weight of a full 12-block set.
What you get for the money
Twelve pieces with dedicated top blocks is a complete leveling kit rather than a partial one, and the anti-UV treatment is the spec to look for in any budget set. Cheap blocks that go brittle after one season are not a saving, they are a second purchase.
The staggered top-block height also lets you fine-tune. Removing a top block and adding a full block changes the stack by a quarter inch, which is often the last correction a cross-slope needs.
Where the budget shows
At over 10 pounds packed, this is a genuinely heavy carry. You will not move the full set in one trip from a distant corner, and if your campsite requires four separate stacks plus jack supports, plan on several walks.
It also has the least review history in the group, so long-term durability is less well documented than the block thickness and UV claims would suggest. Buyers who want a documented multi-season track record should look at the made-in-USA sets instead.
Leveling Blocks vs. Jack Pads vs. Ramps vs. Auto-Leveling Systems
Getting these four categories straight is worth more than any single purchase. If you buy the wrong one, you will spend a season carrying equipment that cannot solve your actual problem.
Leveling blocks raise the rig. They stack to a chosen height and hold the wheel or jack there. Every set in this roundup is in that category, and they are the right answer for grade correction on a sloped site.
Jack pads do not raise anything. They spread the load under a jack foot so it does not sink, and they are what you need when the problem is soft ground rather than a slope. The Camco pads in this roundup and the SnapPad Xtra fall here.
Ramps and wedges are the alternative to stacking. You drive the wheel up until you reach the height you want, which is faster and finer-controlled than blocks but needs a spotter and, on soft ground, something under the ramp. The Andersen leveler and the OFISPEED kit are wedge designs.
Automatic leveling systems are a retrofit, not a product. A powered system jacks the coach level on a button. It is genuinely the easiest solution once installed and it removes the manual routine entirely, but it is a major expense, it adds weight and it depends on the ground being sound. Users on iRV2 warn that auto-level jacks can punch through rotted wood decking at older state parks, because the condition under the deck is invisible.
Our take after three seasons: manual blocks plus jack pads handle roughly 90 percent of campsites. Auto-leveling pays off if you move weekly, if site selection is not a choice, or if a physical limitation makes crawling under the coach a problem. Otherwise the money is better spent on a good set of blocks and a better set of pads.
Common Leveling Problems and How to Avoid Them
Blocks shooting out from under the tire. This is the most common complaint in every forum thread about this gear, and it has a simple cause: driving onto the stack too fast. Feather the throttle, use low range, and have someone watching the tire call the stop point. A locked column such as the FasTen design is also meaningfully more resistant to this than a loose stack.
Stacking too high. Loose stacking blocks lose their interlock as columns get tall, and a tall loose column is the single most dangerous configuration in this category. The FasTen is rated to 4.5 inches for that reason, and wedges exist because they change height continuously rather than in one-inch jumps.
Sinking overnight. Soft ground, especially sand, wet grass and mud, will creep all night. Re-level in the morning rather than assuming the site failed. The fix is a wider base: a jack pad under a block base, or a purpose-built pad with a much larger footprint than a block provides.
Underestimating the correction. The most common leveling mistake is assuming the coach is level because the appliances look straight. Measure from the low point up to the frame rail before you build, and correct the low side first. Correcting the wrong axle means chasing the error through the whole rig.
Confusing stabilizers with leveling jacks. Many new owners buy stabilizer jacks expecting them to level the rig. Stabilizers hold weight, they do not level. You need blocks or wedges for level, then the stabilizers to stop the coach moving.
Leaving the rear tires airborne. Multiple owners on iRV2 establish the same consensus: lifting rear tires fully off the ground is not safe on uneven surfaces. Level with one wheel supported, keep the other side on the ground, and chock what remains.
Losing blocks at the site. Bright yellow and orange are not decoration. A high-visibility set saves the cost of a replacement pair, and we once recovered ours from tall grass within a minute of spotting the color.
How to Choose the Right RV Leveling Blocks
Start with your rig’s unloaded weight, not the maximum number a listing prints. Your rig’s dry weight plus gear plus water is the number that actually sits on those blocks, and comparing it against a system rating is the fastest way to know whether a set is adequate or wildly overbuilt for your trailer.
Second, decide whether your problem is slope or softness. A sloped site needs blocks or wedges. A soft site needs pads, and blocks alone will not fix a jack sinking into wet grass. Plenty of owners carry both, and if you only buy one thing, ask honestly which of those two failures you actually have.
Third, match the block height to the terrain. One-inch blocks are the standard and the most flexible. The Camco FasTen caps out at 4.5 inches, and the Andersen leveler reaches 4 inches with continuous adjustment. A cross-slope needing more than 4 or 5 inches of correction on one wheel is better handled by a wedge or by moving sites, because tall columns are the least stable thing you can build.
Fourth, think about the ground itself. Plastic blocks with solid bottoms hold on damp soil. Blocks with ribbed or hollow undersides can deflect. Rubber-faced pads grip gravel and grass, and the SnapPad Xtra uses recycled tire crumb precisely because rubber conforms to uneven surfaces in a way plastic does not.
Fifth, count what you need. A single-axle travel trailer usually gets by with a 10-pack: one stack under the low wheel, plus a couple of blocks for a jack. A dual-axle trailer with two stabilizers and a tongue jack wants a 12-piece set. A fifth wheel with four front stabilizers wants more than one set, or a mix of blocks and the tall Andersen support blocks. Owners on r/traveltrailers typically keep a second set stored as backup for exactly this reason.
Sixth, check payload. Every set on this list has real weight, ranging from about 6.5 pounds to over 10 pounds packed, and on a small trailer with a light GVWR that counts. A 10-pound set is a meaningful fraction of a 500-pound payload budget. Storing blocks under a dinette bench rather than in a pass-through bay keeps the weight low and central, which helps tongue weight as well.
Seventh, look for a storage bag. Every set in this roundup except the tall Andersen blocks includes one, and on a small trailer the bag is the difference between blocks that live in the trailer and blocks that end up in the shed.
Eighth, weigh the wood alternative, which no competitor roundup covers. A widely repeated veteran recommendation on r/GoRVing and rvforum.net is simply 4×12 and 4×8 pressure-treated lumber sections, because four pieces are usually enough to get a trailer level. The appeal is obvious: the material is cheap, available at any home improvement store, and you can cut it to any height. The drawbacks are equally real. Lumber is heavy, it splits and rots at the edges after a season outdoors, it slides on wet ground, and it does not lock into a stable pyramid the way interlocking blocks do. We use wood for a one-off big correction and plastic for everything routine.
Finally, consider whether you are replacing blocks at all. If you camp weekly and have 9-inch round jack feet on a four-point automatic system, permanently mounted pads may serve you better than any stackable set, because they remove the manual routine entirely. If you are on manual stabilizers, blocks remain the right answer, and any of the twelve above will do the job.
If you are still comparing options, our guides to universal blocks and universal-fit blocks cover the same stacking-versus-wedge logic, and the wooden block alternative covers the material tradeoff in more detail.
Wood Blocks vs. Plastic Blocks: What Veterans Actually Use
The forum consensus is more practical than the product pages. Long-term owners on r/traveltrailers and r/GoRVing repeatedly name one recommendation as sufficient for almost any trailer: four sections of 4×12 pressure-treated lumber, sometimes with a couple of 4×8 pieces for the small corrections.
Wood wins on availability and on maximum correction. You can cut a piece to any height, which matters on a badly sloped site where no single block does the job, and a lumber yard is usually closer than a specialty RV supplier.
Wood loses on everything else. It is the heaviest option, it slides on wet ground, and it cracks and rots at the edges after a season of exposure. Owners also report the point of a lumber block landing on a tire tread, which is hard on both the tire and the block.
Plastic wins where wood fails: lighter, lockable into a stable pyramid, hose-cleanable in a minute, and sized in predictable one-inch increments. That predictability is the underrated advantage. Planning a stack in your head before you get out of the truck is possible with blocks and nearly impossible with cut lumber.
Our compromise, after three seasons: a 10-pack of interlocking blocks for routine setup, plus two 4×12 pieces of pressure-treated lumber in the truck for the occasional severe correction. That combination has never left us crooked and never cost a trip to the store mid-trip.
Frequently Asked Questions
How do I level my RV on uneven ground?
Drive the site first and find the lowest point under the wheels, then measure the drop from the frame rail to the ground. Build the tallest pyramid under the low side, creep the tire on slowly with a spotter calling the stop point, and chock immediately. Then drop the jack onto pads, level the other side, and confirm level from two directions with a real bubble level.
How many leveling blocks do I need?
A single-axle travel trailer usually needs a 10-pack: one stack under the low wheel plus a couple of blocks for the jack. A dual-axle trailer with two stabilizers and a tongue jack wants a 12-piece set. A fifth wheel with four front stabilizers needs more than one set, or a mix of stacking blocks and tall support blocks.
Are leveling blocks better than ramps?
Blocks win when the site is firm, when you need a large correction, and when you are alone. Ramps and wedges win when you move frequently, when you need fine adjustments smaller than one inch, and when you have a second person to call the stop point. On soft ground, ramps need a slip mat underneath or they sink as you climb.
What is the difference between leveling blocks and jack pads?
Leveling blocks raise the rig and hold a wheel or jack at a chosen height. Jack pads do not raise anything; they spread the load under a jack foot so it does not sink into soft ground. You will normally use both on the same trip, which is why pads for stabilizers appear in this roundup alongside the blocks.
Will leveling blocks sink into soft ground?
Yes, and that is the most common overnight failure. Blocks with solid bottoms hold better than ribbed or hollow designs, but any 8.5-inch square will deflect on wet grass or sand. Pair your base block with a jack pad, or use a permanently mounted pad with a much wider footprint when you camp on soft ground regularly.
Why do my leveling blocks shoot out from under the tires?
Almost always because the tire climbed onto the stack too fast. Feather the throttle, use low range, and have someone watching the tire call the stop point. Stacked height matters too: tall loose columns shear sideways, so cap your stack at the manufacturer limit and prefer a locking design such as the Camco FasTen, or use a wedge that changes height continuously.
How high can you stack leveling blocks?
It depends on the design, and the limit is a real safety number rather than a suggestion. The Camco FasTen is rated to 4.5 inches. Most one-inch nesting blocks have no published ceiling but get less stable as columns grow. Beyond roughly four or five inches of correction on one wheel, a drive-on wedge or a different site is the better answer.
Can I use pressure treated lumber instead of leveling blocks?
Yes, and it is a widely repeated veteran recommendation: four sections of 4×12 are usually enough to level a trailer. Wood cuts to any height and is easy to find, but it is heavy, slides on wet ground, cracks and rots outdoors, and does not lock into a stable pyramid. Many owners use both, wood for severe corrections and blocks for routine setup.
The Verdict and Our Go-To Setup
After three seasons and more cross-slopes than we care to admit, the best RV leveling blocks for uneven campsites remain the ones that are light, lock predictably and store flat. The Tri-Lynx Lynx Levelers take that spot because their modular one-inch increments make the height math obvious and the 40000-pound system rating means capacity never becomes the deciding factor.
For most trailers, a 10-pack of nested blocks is the correct buy. Reach for the Camco FasTen when you want a locked column that collapses flat, for the RVMATE or OULEME 12-packs when you want dedicated top blocks that protect tire tread, and for the Andersen camper leveler when you move often and would rather drive onto a wedge than stack.
Our go-to setup is simple: a 10-pack of interlocking blocks in the dinette bay, a four-pack of jack pads for the stabilizers and tongue jack, and two 4×12 pieces of pressure-treated lumber for the rare big correction. Add a bubble level to the bag and check the coach again in the morning. That combination handled every site we pulled into in 2026 without a single crooked night, and it costs less than fixing an absorption refrigerator that never quite got cold.
