7 Best RV Sewer Hose Supports for Better Drainage (2026)

Finding the best RV sewer hose support matters most after a hose sags in the middle and traps waste halfway to the drain. Even a good hose fails at its one job if it sits on rough ground. It also fails if it dips below level anywhere along the run.

A sewer hose support does one thing. It lifts the hose and holds a steady downhill slope from your RV’s outlet to the dump inlet. Which one you need depends on hose length, campsite terrain, storage space, and how often you use full hookups, not just brand loyalty.

This guide compares seven supports across accordion, sectional, and adjustable designs, using manufacturer specifications wherever we could find them, and flags it clearly anywhere a product’s marketed length doesn’t match its physical footprint.

How We Chose These RV Sewer Hose Supports

We have not physically tested all seven of these supports. The rankings below come from manufacturer product pages first, current retailer specifications where a manufacturer didn’t publish something, and recurring feedback from RV owner forums.

Individual forum complaints get treated as examples, not proof that a design fails widely. Where sources disagree on a number, we say so instead of guessing. Manufacturer-published dimensions carry more weight than Amazon bullet points. Amazon reviews come last, used only as anecdotal color.

What Is the Best RV Sewer Hose Support Overall?

The Camco Sidewinder 20-foot support (model 43052) is the best RV sewer hose support for most owners. Its telescoping accordion design flexes around obstacles. Its deep cradles hold a hose without straps, and Camco backs it with a 12-month warranty.

The Sidewinder wins mostly on flexibility. It’s a hinged accordion instead of fixed troughs, so it curves around trees, fire rings, or picnic tables instead of forcing you to route the hose around them. Camco’s current product page lists it at 6.53 pounds, stored in about 13 by 9.25 by 10.25 inches, small enough for most storage bays.

It also isn’t the only 20-foot Sidewinder SKU on the market. An authorized Camco dealer listing for model 43051 describes the same telescoping, 20-foot design as the current 43052, so either SKU is legitimate. Confirm whichever Amazon listing you’re buying shows the 20-foot length and telescoping cradle design before ordering.

A support only solves the slope problem. If the hose itself is old, leaking, or too short for your usual sites, start with our best RV sewer hose guide first.

The 7 Best RV Sewer Hose Supports Reviewed

Camco Sidewinder 20-Foot Support (43052): Best Overall

Hinged accordion sections expand to the hose’s full length. They curve wherever the ground or a fire ring gets in the way. Camco’s current product page lists the 20-foot version as model 43052. An authorized Camco dealer still carries the earlier 43051 SKU for what appears to be the same 20-foot design. Confirm whichever Amazon listing you buy actually shows the 20-foot length and telescoping cradle style. The cradles run deep enough that Camco markets the support as not needing tie-down straps. On genuinely rocky or sharply uneven ground, though, hinged plastic sections can rack sideways more than a rigid trough kit would.

• Type: Telescoping accordion | Supported length: 20 ft | Material: Plastic, no-rust hardware
• Storage: Folds to about 13″ x 9.25″ x 10.25″ | Warranty: 12 months from purchase with receipt (Camco)

Best for: Most RVers who want one support that works at nearly any site Skip if: Your site is genuinely rocky or has sharp elevation changes Key advantage: No straps needed, deep cradles, a 12-month warranty Main drawback: Confirm which SKU (43051 or 43052) the Amazon listing ships before buying

Beech Lane 20-Foot Support: Best for Compact Storage

Beech Lane built this support to nest smaller than competing designs. That’s the entire pitch. Flippable cradle sections give two height options, depending on how much drop you need. The hinge pins are nylon instead of metal, which sidesteps rust rather than just resisting it. Beech Lane backs the support with a lifetime warranty. It sells through its own Amazon storefront rather than a network of RV retailers, so returns route through Amazon instead of a parts department. The company’s product page lists a design patent (No. 11,821,551) on the nesting mechanism.

• Type: Nesting, flippable-height cradle | Supported length: 20 ft | Material: Rust-proof nylon hinge pins
• Storage: Nests smaller than accordion designs; exact dims not published | Warranty: Lifetime (Beech Lane)

Best for: Owners with a tight storage bay who still want the full 20 feet Skip if: You want a wide dealer network behind your warranty Key advantage: Patented nesting design and a lifetime warranty Main drawback: No published folded dimensions, so storage size isn’t directly comparable

Camco Rhino RV Sewer Hose Support Kit (43072): Best for Uneven Ground

Five separate nesting sections replace the Sidewinder’s connected hinges, each with a graduated height, ranging from about 8.5 to 10.5 inches, that lets you position them independently across uneven terrain. According to detailed retailer specifications, each section measures 24 3/16 inches long. That independent positioning handles a curb, a root, or a lumpy campsite better than a support that flexes as one connected piece. Camco’s own product page rates this kit for hoses up to 15 feet, not 20. That’s worth knowing, since it’s a natural pairing for a 20-foot RhinoFLEX or RhinoEXTREME hose kit. The support covers 15 feet of your run. Any extra length on a longer hose sits unsupported unless you add a second kit.

• Type: 5 separate nesting sections, graduated heights | Supported length: Up to 15 ft (Camco) | Material: UV-stabilized polymer
• Storage: Nests, about 9.6″ x 24.2″ x 10.5″ boxed | Warranty: 12 months from purchase with receipt (Camco)

Best for: Sites with real terrain changes, curbs, or turns to navigate Skip if: You need one support to cover a full 20-foot hose end to end Key advantage: Graduated section heights positioned independently handle terrain a connected accordion can’t Main drawback: Rated for 15 feet, shorter than the 20-foot hoses it’s commonly sold alongside

Valterra Slunky 20-Foot Support (S2000): Best Reinforced Accordion

The Slunky answers the same accordion idea as the Sidewinder. The real difference is construction: Valterra’s current design uses metal hinges instead of plastic ones, which the company markets for extra strength. The ridged bottom is meant to grip the ground rather than slide. Six tie-down straps come in the box for wind. Height is fixed rather than adjustable: 4.5 inches at the sewer end and 7 inches at the RV end, per Valterra’s own product page. That’s a real slope built in. It’s just not something you can dial up for a steeper drop the way a staked, adjustable kit lets you.

• Type: Metal-hinge accordion | Supported length: 20 ft | Material: Plastic with metal hinges, ridged bottom
• Storage: Self-fastening strap; dims not published | Warranty: On request from Valterra; not clearly published

Best for: Owners who want an accordion support with metal hinges instead of plastic Skip if: Your site needs more than about 2.5 inches of built-in drop Key advantage: Metal hinges and a ridged, grippy bottom Main drawback: Fixed height range, with no way to adjust the slope further

Camco Adjustable Sewer Hose Drain Support Kit (43071): Best for Difficult Elevation

Reach for this one when your site’s sewer inlet sits well above or below your RV’s outlet. According to an authorized Camco dealer’s specifications, six troughs, each 30 inches long, stake into the ground for up to 10 inches of elevation. Left unstaked, they sit at a lower 1.75 to 4-inch rise. That’s the widest range on this list. Camco and its retailers rate the kit for hoses up to 20 feet, and that’s the figure we’re using here. Worth knowing: the six troughs measure 30 inches each, which adds up to 15 feet of continuous surface. The rest of a 20-foot hose sits between troughs or hangs past the last one. This kit supports key points along the slope, not every inch.

• Type: 6-trough adjustable cradle, 4-point stakes | Supported length: Up to 20 ft (Camco); troughs total 15 ft
• Storage: Nests, about 30.5″ x 12.4″ x 9.8″ boxed | Warranty: 1 year (Camco)

Best for: Full-hookup sites with a genuinely awkward elevation between outlet and inlet Skip if: You want one continuous surface under the entire hose Key advantage: Widest height adjustment on this list, up to 10 inches staked Main drawback: Troughs don’t touch end to end, leaving gaps between support points

Kohree 20-Foot RV Sewer Hose Support: Best Multi-Length Option

Thetford’s Titan Sewer Hose Support, a common alternative in this category, is now listed as discontinued on Thetford’s own site, so we replaced it here with a current, actively sold option.

Kohree’s own product page lists the support in high-impact PP plastic with a deep U-shaped cradle and a detachable-buckle height adjustment, rated for hoses up to 20 feet. The same product line also comes in 10-foot and 15-foot lengths, so you can size the support to your hose instead of buying one universal length. Each section measures 7.56 by 8.66 inches, per Kohree’s specifications, and the kit ships with a carrying strap and a 12-month warranty. That warranty runs through Kohree directly, not through an RV dealer network like Camco’s or Valterra’s.

• Type: Height-adjustable accordion, deep U-shaped cradle | Supported length: Up to 20 ft (Kohree) | Material: High-impact PP plastic
• Storage: Folds with carrying strap; sections measure 7.56″ x 8.66″ | Warranty: 12 months (Kohree)

Best for: Owners who want to match support length exactly to a 10, 15, or 20-foot hose Skip if: You’d rather have warranty and parts support through an established RV dealer network Key advantage: Sold in three lengths from one product line, so sizing is exact Main drawback: Newer to the market than the Camco and Valterra options, with less independent, long-term owner feedback

Camco Aluminum Folding Sewer Hose Support (40351): Best Metal Support for Short Runs

This is the only rigid metal option on the list, and it’s built for a different job than the other six. An authorized Camco dealer’s listing markets it as compatible with hoses up to 10 feet. The support itself telescopes to only 6 feet of actual length, though, and folds to 6.75 inches. Solid brass rivets resist rust, and a strap kit is included. If you need more reach in an aluminum design, Camco also sells a 15-foot version (model 40353). According to a retailer listing for that model, it extends further and folds to about 10.5 inches. That one isn’t part of this shortlist, but it’s worth knowing about if the 6-foot reach here is the dealbreaker.

• Type: Rigid folding aluminum | Supported length: Marketed for 10-ft hoses; extends to 6 ft | Material: Aluminum, brass rivets
• Storage: Folds to about 6.75″ | Warranty: Not clearly published; check with Camco

Best for: Short dump-station hops or a close full-hookup connection Skip if: You regularly need to cover more than 6 feet of open ground Key advantage: Rigid aluminum construction with rust-resistant brass rivets Main drawback: Marketed hose compatibility (10 ft) exceeds the support’s actual reach (6 ft)

Which Type of RV Sewer Hose Support Is Best: Accordion, Sectional, or Adjustable?

Accordion supports like the Sidewinder, Slunky, and Kohree work best for most campgrounds and set up fast. The Camco Rhino’s separate graduated sections handle real elevation changes better. Beech Lane’s hinged nesting design trades some terrain flexibility for smaller storage. Adjustable stake kits like the Camco 43071 win when a site’s slope is genuinely difficult, and metal folding supports only make sense for short runs.

Accordion (Sidewinder, Slunky, Kohree): fastest to set up and store, though hinges can rack sideways on rough ground.

Independent sectional troughs (Camco Rhino): five separate sections with graduated heights that position independently, handling uneven terrain and curbs better than a connected accordion. The tradeoff is setup time and a 15-foot rating shorter than the 20-foot hoses it’s often paired with.

Nesting, hinged design (Beech Lane): flippable sections nest together for storage rather than acting as independent troughs, built around compact storage first.

Adjustable cradle (Camco 43071): ground stakes give up to 10 inches of elevation, more than double any accordion or fixed sectional support, with gaps between troughs as the tradeoff.

Metal folding (Camco Aluminum): rigid rather than flexible, good for a short, close hookup, limited everywhere else by its 6-foot reach.

Start with an accordion support for a typical weekend site. Step up to the Rhino or the 43071 for curbs or real elevation changes. Choose Beech Lane if storage space is tight, and save the aluminum folding support for short hookups.

What Length RV Sewer Hose Support Do You Need?

Match the support to the parts of your hose run that actually need lifting, not necessarily the hose’s full length. A 20-foot sewer hose doesn’t always need 20 feet of support underneath it, but any unsupported section still needs to avoid sagging into a low trap.

Campsite sewer-inlet placement varies between campgrounds, and older parks sometimes need every inch of a 20-foot run. Longer isn’t automatically better, though; a support that’s harder to store than it’s worth using ends up staying in the bay.

6-foot support: A short, close hookup, or a spot fix for one low section (Camco Aluminum’s actual reach)

15-foot support: A moderate campground run, or a 20-foot hose where only part of the length sags (Camco Rhino, or Kohree’s 15-foot version if you want to size down)

20-foot support: The safest all-around size for most full-hookup sites (Camco Sidewinder, Valterra Slunky, Beech Lane, Kohree’s 20-foot version, or the Camco 43071’s rated coverage)

We didn’t find a published regulation or plumbing standard for an exact required slope on RV sewer hoses. What you’re aiming for is a steady, continuous downhill drop with no low spots, not a specific number of degrees.

Do You Really Need an RV Sewer Hose Support?

Not always. But a support solves a specific problem: it lifts your hose off rough ground and keeps a continuous downhill path so waste doesn’t pool in a sag. Whether you need one depends more on your site than on any universal rule. Some campgrounds and cities do require elevated sewer hoses as local policy, but that isn’t a nationwide requirement, so check the specific site’s rules if you’re unsure.

A support matters most at full-hookup sites where the hose stays connected, on uneven ground, on long hose runs, at a raised sewer inlet, or during extended stays.

It matters less for quick dump-station use, a short and naturally downhill run, or a macerator system. A macerator uses a different discharge setup than a gravity hose; see our macerator pump vs. sewer hose comparison if you’re weighing the two.

If a hose still drains slowly after you’ve eliminated every low spot, the problem is more likely upstream. Check our guide to an RV black tank not draining before you blame the support. And if you’re a full-hookup camper, remember that leaving the black valve open between dumps builds solid waste into a pyramid plug no support can fix.

Conclusion

For most owners, the Camco Sidewinder 20-foot support is the easiest overall pick: flexible, compact, and backed by a solid warranty. The Camco Rhino’s graduated, independently positioned sections handle curbs and elevation changes better. Beech Lane is our compact-storage pick thanks to its nesting design, and Kohree lets you match support length exactly if you’d rather size down from 20 feet.

Whichever you choose, the decision comes down to four things: hose length, site terrain, storage space, and how often you deal with full hookups. Get those four right, and any of the seven supports here will keep waste moving downhill instead of pooling where you don’t want it.
