10 Best RV Sewer Hose Kits for Travel Trailers (October 2026) Complete Guide

Short answer: the Camco RhinoFLEX 20-Ft Complete Kit is the best RV sewer hose kit for most travel trailers, because two 10-foot sections that each compress to 39 inches give you 20 feet of reach and still slide into a hollow rear bumper. The Camco Revolution 10-Foot Kit is the budget pick if you only ever dump at sites with a nearby station. The Thetford Titan 15-Foot is the premium pick for owners who want a hose that survives being run over.

That is our shortlist for the best RV sewer hose kits for travel trailers in 2026, and every pick below is scored on the things a trailer owner actually feels: collapsed length against a 4-inch bumper tube, wall thickness in mils, minimum temperature, and whether the fittings can ever separate from the hose. We also read a large volume of owner reporting on r/GoRVing, r/RVLiving and r/rvlife so the cons are real ones, not filler.

Top 3 Picks for Best RV Sewer Hose Kits for Travel Trailers

Two things decide most trailer purchases, and both are in that top 3. First, collapsed length. The RhinoFLEX sections compress to 39 inches, which is the number that matters when your storage tube is a 4-inch square bumper and your trailer is a bumper-pull. Second, whether the fittings are permanently attached. The Thetford Titan and the Valterra Dominator both bond their fittings to the hose, which is the direct answer to the most common owner complaint on these forums: fittings separating in service and tape not fixing them.

All 10 Travel Trailer Sewer Hose Kits at a Glance in 2026

Two compatibility facts explain almost every fit question in this category. Standard RV sewer hoses are 3 inches in diameter with lug and bayonet fittings, so they mate with the discharge valve on nearly every travel trailer ever built. The exception is the Lippert Waste Master, which uses a CAM lock connector and is not a drop-in replacement for a standard bayonet outlet.

1. Camco RhinoFLEX 20-Ft Complete Kit — Best Overall for Travel Trailers

This is the kit we keep coming back to, and the reason is unglamorous: it is the one travel trailer sewer hose that solves storage and reach at the same time. You get two 10-foot sections, and each one compresses to 39 inches. That is short enough to live in a hollow 4-inch bumper tube rather than a wet bay that is already crowded with the jack handle and spare tire.

The hose itself is 23-mil polyolefin reinforced with steel wire at a 3-inch outside diameter. Owners consistently describe it as holding its bend instead of sagging into a low spot, which matters when you are crossing a gravel pull-through to reach a station on the far side.

The clear elbow is the reason we rated this the best travel trailer sewer hose kit overall. You can see the last of the black water leaving the tank and know exactly when to stop, instead of guessing with a hose you cannot see into. The 4-in-1 adapter inside it fits 3-inch slip and 3-inch, 3-1/2-inch and 4-inch threaded dump station pipes.

Fittings swivel 360 degrees at both ends, so the connection to a high station inlet is not a wrestling match. The whole kit weighs 5 pounds and is made in the USA, and the fit is backed by more than 22,000 reviews with an average of 4.7 stars.

Will the RhinoFLEX fit a 4-inch bumper tube?

Usually yes, and this is the section that decides it for most trailers. With each 10-foot section compressed to 39 inches, two sections stack to about 6.5 feet, which is a realistic length for a rear bumper storage tube on a mid-size travel trailer. Smaller pop-ups and teardrops often have a shorter tube, and there you may only fit one section.

The clear elbow does not slide into the tube, so owners either cap and pocket it or hang it in the wet bay. That is a small inconvenience, but it is worth knowing before you buy.

Where the RhinoFLEX is not the right pick

If you have a trailer with no rear storage tube at all and a very shallow wet bay, the thinner Valterra and Revolution hoses compress shorter and win. And if you are on a hard budget, the whole RhinoFLEX package is more hose than many first-time owners ever need for a 10-foot site.

One more caution from owner reports on r/GoRVing: a small number of owners have reported fitting separation on RhinoFLEX units bought in recent production runs, while older units keep working. That is exactly the pattern we discuss in the failure section below.

2. Camco Revolution 10-Foot Kit — Best Budget Pick

Most of us are handed a starter hose by the dealer, and the recurring line in the owner threads is that it is not worth keeping. The Camco Revolution is the standard replacement, and for a trailer that only ever dumps within 10 feet of the station, it does the job with none of the bulk.

At 2 pounds it is the lightest kit in this roundup, and it compresses to 24 inches, which means it disappears into almost any storage tube or bay. The pre-attached 360-degree swivel fittings mean there are no clamps to lose in a wet bay, and the wire guards protect the hose ends where they take the most abuse.

The tradeoff is honest and simple. This is 15-mil HTS vinyl, against 23 mil on the RhinoFLEX and 24 mil on the DUMPMAN kit, and wall thickness is what stands between you and a puncture from a sharp rock at a gravel site. There is also no clear elbow, so you open the valve and wait without being able to watch the tank empty.

It holds a 4.5 rating across more than 5,000 reviews, with buyers citing the swivel fittings and the short compressed length as the main reasons to keep it.

When 10 feet is genuinely enough

Most campground dump stations sit within about 10 feet of your pad, and pull-through sites often put the station right at the exit lane. If you camp in one place all season, a 10-foot kit is a real answer rather than a compromise, and this is the cheapest way to stop worrying about a slow leak.

Owners on r/GoRVing who workamp and move weekly also tend to carry two 10-footers rather than one 20-footer, because winding a long hose around to a station five feet away is genuinely awkward.

When you need to move up a tier

If you ever boondock and travel between dump stops, or if you dump with a trailer that has a long rear overhang, 10 feet turns into a walk around the corner with an open valve. At that point the Valterra EZ Coupler 20-foot kit gives you the same storage footprint in two pieces and a longer reach.

The other reason to skip this one is thin-wall durability. At 15 mil it is the second-thinnest hose here, and a single puncture ends the trip.

3. Thetford Titan 15-Foot Premium Kit — Best for Rough Ground and Cold Weather

The Thetford Titan is the answer to the question every owner eventually asks: what is the toughest RV sewer hose? The hose is thermoplastic elastomer rather than vinyl or polyolefin, and one reviewer on the product page reported driving a leveling jack onto it with no leak at all. That is not a stunt we would copy, but it tells you how the material behaves.

The fittings arrive fused to the hose ends and use large-diameter screw threads with a non-hardening silicone gel seal. Because the fittings are bonded rather than clamped, they cannot work loose, which removes the single most common failure mode owners report elsewhere in this category.

The Revolve 5-in-1 adapter is the smartest piece of hardware in this roundup. It fits any RV sewer outlet and rotates, so you can approach a dump station that is at an awkward height or behind you without fighting the hose.

TPE does not compress the way vinyl does, though. Packed, the kit measures about 95 inches, which will not fit a short bumper tray, and several buyers describe the adapter handle as flimsy even while they rate the hose itself highly.

How this holds up in freezing weather

Because it is TPE, the Titan resists going brittle in cold conditions and in hot sun, which matters for full-time campers and winter campers who store a hose in an unheated bay. Most polyolefin hoses are fine down to around minus 20 degrees F, and this one is not advertised with a specific minimum figure, so check the listing if you camp in deep cold.

The trade is storage. If you have a deep wet bay, the 95-inch packed length is a non-issue. If you rely on a bumper tube, this is the wrong kit.

Where owners report trouble

Critically, most negative reports on this kit target the adapter, not the hose. Several detailed accounts describe the elbow separating from the hose-to-screw-thread joint when the line is at full extension and under tension at a distant station. If you use 15 feet at full length, support the run or relieve tension at the fitting.

That is the trade for permanently bonded fittings: you lose the ability to replace a fitting yourself, and Thetford sells replacement seals separately.

4. Valterra Dominator 15-Foot Kit — Best Shape-Holding Hose

Shape-holding is the Dominator’s defining trait. The 23-mil hose is pre-installed with bayonet hooks that keep it flat, and owners describe it as climbing curbs and high dump ports without sagging into a puddle in the middle. On a campground site with an uneven surface, that rigidity is a genuine advantage over a floppy vinyl hose.

The fittings are permanently attached, so they cannot work loose in service, which is the same leak-proof argument that makes the Titan appealing. The transparent 90-degree ClearView adapter fits six sewer types with a gas-tight seal, and it doubles as the monitor that tells you the black tank is fully rinsed.

At 15 feet it sits between the 10-foot and 20-foot options, and it collapses to 57 inches. That is longer than the compact two-section kits but shorter than the Titan, and it packs to roughly 24 by 8.75 inches.

The rating is 4.6 across more than 2,400 reviews, anchored by long-horizon owners reporting years of leak-free service. The same shape-holding behavior is what makes it feel different in the hand from a cheap hose.

Is the ClearView adapter worth having?

Yes, in a way that pays for itself the first time you use it. Dumping until the water runs clear is the correct procedure, and a translucent elbow means you stop on evidence rather than on a count of seconds. Owners switching to kits with permanently attached fittings are usually switching because of leaking swivel joints, and this one answers both complaints at once.

The catch is storage. The 90-degree adapter will not fit inside a square bumper, so it has to be capped and carried separately, same as the RhinoFLEX elbow.

What the single-section format costs you

Sold as one 15-foot section, the Dominator cannot be split into two shorter runs. If the dump station is close, you are still winding 15 feet of hose, and owners on r/RVLiving who prefer short sections for exactly that reason tend to choose the two-piece kits instead.

The other caution: one reviewer testing six sections found two that leaked, so water-test a new kit before the first real dump.

5. Valterra EZ Coupler 20-Foot Kit — Best for Short Bumpers

This is the answer for pop-ups, teardrops and any trailer with a cramped storage tube. Each 10-foot section collapses to 25 inches, which is the shortest packed figure in this roundup, and the sections detach so you can carry just one when the station is close.

The pre-installed rotating bayonet fittings form a leak-proof connection, and the transparent 90-degree ClearView adapter fits six sewer types. At 1.9 pounds it is the second-lightest kit here, which matters when you are lifting it over a low bumper.

The 20-mil-versus-18-mil question is where this kit gives ground. The wall is 18-mil vinyl, the thinnest in our group, and the 76 percent five-star share is the second lowest among the 20-foot kits here. Buyers like the two-piece format; the durability complaints almost always trace back to the lighter material.

It still holds a 4.5 rating across more than 2,200 reviews, and the design is well established.

When two short sections beat one long hose

The recurring owner consensus on r/GoRVing is that two 10-foot sections are more useful than a single 20-footer, and this kit is built for that. Winding 20 feet of hose around to a hookup five feet from your pad is one of the most complained-about tasks in RVing, and with detachable sections you just use one.

Its 20 feet of reach also breaks into two packable pieces, and the short collapsed length means a wet bay that is already full stays usable.

Where the thin wall will bite

Eighteen-mil vinyl on gravel, dry campsites and forest roads is where the complaints live. Owners describe abrasion and pinhole risk, and detachable fittings add joint points that can weep after years of use. If you camp on sharp ground regularly, the DUMPMAN kit at 24 mil is a better use of the same two-section format.

One more practical note: the ClearView adapter will not slide into a square bumper, so budget a pocket for it.

6. DUMPMAN 20-Foot Kit — Best Wall Thickness

Wall thickness is the least glamorous spec on this list and the one that decides survival. The DUMPMAN kit runs 24 mil with UV protection and abrasion resistance, the thickest hose in this group, and owners report it springs back into shape after being stepped on rather than taking a permanent crease.

It ships as two 10-foot sections with rotating fittings, a removable transparent 90-degree elbow with a 4-in-1 adapter covering 3-inch slip and 3-inch, 3-1/2-inch and 4-inch NPT station pipes, plus four end caps. Each section collapses to 45 inches, which is still bumper-friendly.

What stands out is the category rank. Despite being one of the more affordable kits here, it holds a top-ten position in RV Sewer Hoses on Amazon, which tells you a lot of owners landed on it by looking at specs rather than brand.

The 4.4 rating is the lowest in this roundup, and the one-star share runs about 6 percent, so expect some noise. With 1,080 reviews it has a smaller evidence base than the legacy brands, which is the main reason it is not our top pick despite the best wall in the group.

Is 24 mil worth the trade?

If you dump on gravel, forest roads or dry campsites, yes. Wall thickness is your only defense against a rock, a root or a gear-shift knob, and 24 mil gives you meaningfully more margin than the 15 and 18-mil kits. The material is described as TPE vinyl, and it handles repeated compression without flattening.

If you dump almost exclusively at paved full-hookup sites, the difference is largely theoretical and the RhinoFLEX is the better-proven buy.

What to watch before first use

Do a water test. Fill the hose and check every joint under a faucet or hose bib before you rely on it at a campground, and inspect the elbow threads where the removable adapter threads in. The listed weight of 2.63 kg looks like package rounding, so do not use it as a carry comparison.

Because the elbow is removable, give it a dedicated pocket in the wet bay. Losing a 4-in-1 adapter at a dump station is a bad afternoon.

7. Lippert Waste Master 20-Foot System — Best Managed System

The Waste Master is not really a hose kit in the same sense as the rest of this list. It is a managed system: the hose extends only to the length you need and holds that length, and it comes with a permanently molded nozzle carrying an integrated shut-off valve and a clear view port. That valve alone changes how you dump, because you can stop flow without reaching for a clamp.

The construction is a helical coil on the outside with a smooth inner bore, so waste does not trap in ridges and the hose rinses clean more easily than an interior-coil design. The hose is UV-protected, 20 feet extended and 5 feet 6 inches compressed.

Here is the gotcha that catches travel trailer owners. The CAM lock connector is not compatible with a standard bayonet or lug discharge pipe. Owners report that installing it required cutting and PVC-cementing the existing RV connection, because it is not a plug-and-play swap. Budget a plumber or a weekend with a pipe cutter if your trailer is not already set up for it.

At 9 pounds it is also the heaviest kit here by a wide margin, and with 546 reviews it has the smallest evidence base in this roundup alongside the Amazon Basics pair.

Who actually benefits from a managed system?

Owners who dump weekly and hate the cleanup, and anyone who has had a blowout. Several people in the owner threads describe real pressure in the line during a dump, and an integrated shut-off valve is the direct answer to that risk. A long-term Foretravel owner on the thervgeeks comment thread reports the Waste Master never leaked, accordions safely without exposed wire, and compresses into the same crate as a cheap hose.

If you dump once a season at a paved site, this complexity buys you very little.

What the premium buys and what it costs

You are paying for the valve, the view port, the smooth bore and the extending-hose design. What you give up is portability at 9 pounds, bumper fit at 5 feet 6 inches compressed, and the ability to install without modifying your trailer. The 4.4 rating with a 9 percent one-star share suggests the system is not flawless, and the 75 percent five-star share is the lowest here.

One year of manufacturer warranty coverage is included, which is thinner than some owners would like on a system this involved.

8. Camco Deluxe Kit with Wye Connector — Best for Dumping Both Tanks at Once

The wye connector is the single feature no other kit in this roundup has. It joins two hose assemblies into one dump station inlet, so you can empty black and gray together in a single pass rather than moving the trailer or swapping hoses. If your site has one narrow station pipe and you do not want to shuffle, this solves the problem cleanly.

Each 10-foot section carries pre-attached 360-degree swivel fittings with a lug fitting and a four-prong bayonet fitting, so the hose end that meets the trailer and the end that meets the wye are both already assembled.

The 18-mil super heavy-duty HTS vinyl is thinner than the 23 and 24-mil hoses elsewhere in this list, and there is no clear-view adapter, so you dump without being able to watch the tank finish. It also carries a strong demand signal in its own right, sitting near the top of the Amazon RV Sewer Hoses category.

It holds a 4.5 rating with a 78 percent five-star share across 1,495 reviews.

Is dumping both tanks at once worth the extra parts?

If your dump station has a wide or sloped inlet and you run both tanks, yes. One connection, one pull-up position, and the wye distributes flow into both sections. That is a meaningful time saving at a crowded weekend dump area, and a commenter described a macerator as the best upgrade they ever made for exactly this reason.

If your site has a single 3-inch bayonet inlet and you are only draining one tank at a time anyway, the wye is dead weight in your wet bay.

What to check before you commit

Watch the fittings. One owner reported the hose-end fittings working themselves loose over a couple of years, which is the failure mode permanently bonded fittings are designed to prevent. Water-test the assembly before first use and check it again after your first few dumps.

Also pack a spare set of caps. The wye means more connection points, and more connection points means more places to lose a fitting.

9. Amazon Basics 15-Foot Kit — Best Starter Kit

This is the kit to buy if the dealer hose failed, you are replacing it once, and you want a full working set without researching fittings. You get a 15-foot hose, a 90-degree four-in-one ground converter and two hose covers, which is everything you need for a complete dump cycle.

Owners report no leaks across multiple cycles and describe the hose as thick and well made for the price. It stacks compactly for storage, and only one section needs to fit a square bumper because it is a single hose.

The reservation here is evidence, not quality. With 154 reviews, the 4.5 rating is provisional, and a 20-foot sewer hose is something you buy once and trust for years. Some owners feel the plastic is thin, and the elbow is translucent white rather than fully clear, so visibility while dumping is only fair.

Treat it as a capable first kit rather than a long-term answer.

Is a budget kit from a general marketplace brand a risk?

It is a different kind of risk than people assume. The failure that ends your trip is a fitting separating, and a molded one-piece fitting of this type has no threaded joint that can back off. The thinner concern is the wall itself, which the manufacturer does not publish a mil figure for, so you are buying on feel and reviews rather than on a spec.

If you keep it, replace it after two or three seasons of heavy use.

When to buy the 20-foot version instead

Buy the 20-foot version if you ever move between dump sites or have a station set back from your pad. A single 15-foot hose is hard to wind when the station is close, because you are still managing the whole length, and this is exactly the problem the two-section kits solve.

Our RV kitchen gear guide covers the other upgrades most first-time trailer owners prioritize alongside this.

10. Amazon Basics 20-Foot Kit — Best Two-Section Value

This is the version we would pick over the 15-foot kit, and the reason is the format rather than the brand. Twenty feet supplied as two 10-foot sections gives you the routing flexibility that owners consistently ask for, and the kit still includes a 90-degree four-in-one ground converter and four hose covers for storage.

It holds a 4.6 rating with a 79 percent five-star share, the higher of the pair, and it weighs 4.5 pounds.

Two things are missing and both are worth knowing before you commit. No wall-thickness or material specification is published, so you cannot compare it directly against a 23-mil or 24-mil hose. And with 172 reviews, the long-term durability record is thin, which for a product you rely on once a season for years is the real consideration.

The translucent elbow also means you are dumping without a clear view of the last of the tank contents.

How does this compare with the Camco Revolution?

Both compress short enough for a bumper and both use rotating fittings, but the Camco is the more proven buy. It has more than 5,000 reviews, a published 15-mil wall, and a lighter 2-pound carry weight, and it has been in production long enough that failure patterns are well documented.

This kit wins on kit completeness at a budget level, with four covers and a converter in the box.

Who should buy it and who should not

Buy it if you are outfitting a rental or a first trailer, you dump at full-hookup sites, and you want a complete two-section kit without thinking about it. Skip it if you camp on gravel regularly or intend to keep the trailer for a decade, because the unknown wall thickness is the wrong risk for a puncture-prone season.

Either way, water-test both sections before the first real dump.

How to Choose a Kit: Mil Thickness, Material, and Adapters

Mil is simply thousandths of an inch, so 23 mil is about 0.023 inches of wall. That single number tells you more about puncture resistance than any marketing phrase, and the range across this roundup runs from 15 mil on the Revolution to 24 mil on the DUMPMAN kit. Below roughly 18 mil you are choosing a hose that will live a shorter life on rough ground.

Material matters as much as thickness. Polyolefin reinforced with a steel wire coil, as on the RhinoFLEX, is stiff and shape-retaining. Thermoplastic elastomer, as on the Thetford Titan, is the most resistant to crushing and to going brittle in cold weather. Polypropylene and vinyl are lighter and compress shorter, which is often the more important trait in a travel trailer.

Where the coil sits decides how clean the hose stays. An interior coil creates ridges that trap waste and are harder to rinse. An exterior helical coil, as on the Lippert Waste Master, leaves a smooth inner bore that flushes more completely. That difference shows up every single time you rinse the tank, which is often.

What to look for in adapters

A 4-in-1 adapter fits 3-inch slip inlets plus 3-inch, 3-1/2-inch and 4-inch threaded station pipes, which covers nearly every dump station in North America. A 5-in-1 adapter adds a further size or a rotating head. The Thetford Revolve rotates so you can approach an inlet from any angle without twisting the hose.

The clear elbow is worth paying attention to because it is how you know when to stop the dump. End caps matter more than people expect, since a hose that drains into your bumper tube is a hose you will smell for the rest of the season.

How much length do you need

Measure from your trailer’s dump valve to the farthest station you actually use. Most campground stations sit within 10 feet of the pad, which makes a 10-foot kit legitimate. Boondockers, workampers and anyone using state parks or long pull-throughs need 20 feet. The often-repeated 25 to 30 foot request is answered with a coupler, covered below.

Two 10-foot sections are the most flexible answer, and that is why most of this list ships that way.

Will It Fit Your Travel Trailer’s Rear Bumper?

Most travel trailers built with a bumper-pull have a hollow 4-inch square tube designed to hold the sewer hose, and the number that decides fit is the collapsed length, not the extended length. Sections that compress to 24 to 39 inches slide in easily. A kit that packs to 57 or 95 inches does not.

This is the single constraint that no top-ranked competitor page addresses, and it is the one that generates the most returns. Buy the hose first, measure the tube, and only then confirm the collapsed figure.

Two things catch people out. First, the clear elbow and the 4-in-1 adapter are frequently removable and never fit inside a square tube, so they live in the wet bay or in a pocket. Second, a 90-degree adapter is physically too wide for a 4-inch square tube no matter how well the hose compresses.

If your trailer has no storage tube, a wet bay is fine as long as the hose is the lightest thing in it. At 9 pounds, the Lippert Waste Master is the one kit here that dominates a bay, and at 2 pounds the Camco Revolution nearly disappears.

Getting 25 or 30 Feet of Reach With Two Hoses

The 25 to 30 foot request is the most common question on r/rvlife, and it has a simple answer: you do not buy a longer hose, you buy a coupler.

First, close the tank valve and make sure both sections are fully drained and capped before you extend a run that long. Next, connect the bayonet end of section one into the lug end of section two, or use a dedicated sewer hose coupler if you would rather not rely on the hose-to-hose fit. Then route the combined run and support it along its length so it does not drag on gravel.

Two 10-foot sections give you 20 feet of reach with a joint in the middle, and a coupler of the right diameter gives you 30 feet when a station sits at the far end of a long pull-through. A support cradle is genuinely worth carrying at that distance, because an unsupported run sags, sags means pooling, and pooling means the last of the tank does not always leave.

Our travel gear picks cover the small-kit items that make a long dump run less of a chore.

Owner-Reported Failure Patterns by Model

These reports come from owner threads, not from our own testing, and we present them because owners on these forums are specific enough to be useful. Treat them as community reports rather than lab results.

On r/RVLiving and the thervgeeks comment thread, several owners describe RhinoFLEX connection fittings coming apart, with the blunt conclusion that tape does not fix them. The same threads contain a counter-pattern: owners running three Camco Rhino hoses for years while workamping report they held up, handling them only when moving.

The recurring Camco theme is production drift. Owners report newer model-year units leaking within a month, while 3.5-year-old hoses of the same type were only starting to fail. One owner bought three 10-foot Camco hoses in a single year, two from one retailer and one from another, and all three began weeping quickly. That is a pattern worth watching, and it argues for water-testing whatever you receive.

Valterra gets a split verdict. Some owners describe the hoses as thinner and less durable than Camco, while others with a Dominator report years of leak-free service. Detachable fittings in the EZ Coupler are the part most likely to weep over time. On the Thetford Titan, the complaint pattern targets the Revolve adapter, with several detailed accounts of the elbow separating under tension at full extension rather than the hose failing.

On the Lippert Waste Master, the stumbling block is not failure, it is installation. Owners consistently describe the CAM lock as not plug and play, requiring the existing RV discharge connection to be cut and PVC-cemented, which is the single most important thing to know before buying that system for a travel trailer.

Two ergonomic fixes come up repeatedly for owners with limited hand strength. Bayonet fittings are described as almost impossible to make and undo with arthritic hands, and one owner solves it with two adjustable oil-filter pliers turned in opposite directions. The other recurring fix is a pair of nitrile gloves for grip on wet fittings.

Frequently Asked Questions

The Verdict: Which Travel Trailer Sewer Hose Kit to Buy

After working through all ten, the Camco RhinoFLEX 20-Ft Complete Kit is our pick for the best RV sewer hose kits for travel trailers in 2026, because it is the rare kit that solves reach and storage at once. Two sections at 39 inches compressed, 23 mil steel-reinforced polyolefin, a clear elbow so you know when to stop, and the largest review base in the category behind it.

Buy the Camco Revolution if you only ever dump within 10 feet and you want the lightest, shortest option. Buy the Thetford Titan if you camp on rough ground or in cold weather and permanently bonded fittings matter more to you than a compact package. Buy the DUMPMAN 20-footer if wall thickness is your priority, and the Camco Deluxe wye kit if you want both tanks out through one station.

One last practical step: measure your storage tube before you order, and water-test whatever arrives before you trust it at a dump station. That ten minutes costs nothing and prevents the two problems that end RV trips.
