No single support in this group is rated for 40 feet, so this guide covers the closest real sizes and how owners cover a long route with more than one support. A 40 foot sewer run is a big span, often needed at full-hookup sites where the sewer inlet sits far from your outlet, and each support's rated length is a ceiling rather than a suggestion.

The reason supports matter at all is gravity. A sewer hose has to slope continuously downhill, a commonly cited guide is about a quarter inch of drop per foot, or the waste stops flowing and pools in sags. Over 40 feet that is roughly ten inches of fall from outlet to inlet, and an unsupported hose will droop, trap waste and eventually clog or split at the low spots.

Two supports are compared: a telescoping Camco Sidewinder rated for 15 feet and a polypropylene Kohree accordion for 20 feet. Because a 40 foot route needs more than one, the guide focuses on how to combine them: two Kohree supports reach exactly 40 feet, while mixing the two brands reaches about 35. The tables below tie each plan to a named support.

Before you buy

What Matters Before You Choose a 40 Ft RV Sewer Hose Support

Key buying criteria so you get the right fit the first time.

  1. 01

    Rated length and number of pieces

    A 40 foot route needs more than one support, since the longest one here is rated for 20 feet. Rated length is the most each piece can carry, not a target to stretch. Measure the route from the outlet to the sewer inlet along the path the hose will actually take, then divide by the rated length to count supports.

  2. 02

    Continuity of slope

    When two supports meet, the slope must carry across the join. A step or gap collects waste in the hose and starts a clog. A commonly cited guide is about a quarter inch of drop per foot, so over 40 feet you want roughly ten inches of total fall. Set both supports to the same angle and overlap the ends.

  3. 03

    Build type

    Telescoping and accordion supports differ in setup speed, shape flexibility and cost. A telescoping unit slides out to length, while an accordion unfolds and bends to follow the ground. Choose by how often you dump and how curved your route is, and read the product description for the material, such as polypropylene. Material affects how well the support handles sun, cold and the weight of a full hose.

  4. 04

    Storage for several supports

    Two or three supports take real room in a bay, and a hose with sewage residue is not something you want to store loose. Check the folded or collapsed size of each support and plan the space before you buy. Telescoping pieces compress shorter, while accordion pieces fold flat and may stack in a bin. Measure the bay opening so the folded length actually fits.

  5. 05

    Stability on a long run

    A long run is heavier when it carries waste and tips more easily on uneven ground. A deep U cradle holds the hose in place, and a stable base resists rolling. Read the cradle description on each support, look for adjustable height settings, and set the supports on firm ground rather than loose gravel or soft soil. A flat pad beneath the low end keeps the cradle from tilting sideways.

Best for: Owners wanting a branded telescoping segment

Our take

Best for owners who want a recognized branded unit as one segment of a long run.

Why it made the shortlist

Gravity flow drives the design of the Camco Sidewinder 15 foot support, a plastic cradle that extends and folds. It curves around obstacles such as a tree root, a water spigot or a curb, and it compresses for storage, so a single unit fits easily in a bay.

In return, the telescoping extension is faster to deploy than an accordion fold: you pull it out to length instead of unfolding and straightening each section, which saves minutes at every stop. A branded product is also widely stocked, making a replacement easy to find.

Paired with a second support, it can reach into the 35 foot range, and it works well as the section nearest the rig where a quick, tidy setup matters most. A solid building block for a multi-support plan.

What works

  • Quick to extend
  • Branded and widely stocked
  • Compresses for storage

Best for: Owners covering the most length per support

Our take

Best for covering the most length per support.

Why it made the shortlist

Kohree makes its 20 foot support from polypropylene in an accordion form, with a deep U cradle and height settings. It needs no assembly and bends to follow the ground, so you can curve the hose around a post or a pad corner while keeping the downhill slope.

It costs $10 less than the Camco and covers five more feet. Two of these supports reach exactly 40 feet for $79.98, which is the neatest way to cover a 40 foot run with a single product line.

If your route is long and you want the fewest pieces, the lowest cost per foot and a single matching pair, this is the stronger base for a 40 foot plan. A good value segment that also stores flat in a bay.

What works

  • Longest span here
  • Polypropylene named

  • Covers only 20 feet
  • No stakes or ropes

Methodology

How We Built This Shortlist

Each pick was assessed across 4 criteria weighted for real-world use.

01

Real rated length

We noted that no support is rated for 40 feet, and we compared the stated lengths of 15 and 20 feet. Based on published specs, a 40 foot route needs more than one piece, so we counted how many supports each plan takes.

02

Build type

We compared a telescoping plastic cradle with a polypropylene accordion. Each style sets up and packs away differently, and the cradle shape decides how well the hose stays seated and how smoothly it can curve around obstacles.

03

Modularity

We looked at how supports could be combined end to end for a continuous slope. A support that lines up cleanly with a second one makes a long run workable, while a gap or step collects waste in the hose.

04

Storage and cost per foot

We compared folded size and price against the length each support covers. Two or three supports take real room in a bay, so compact storage and a low cost per foot both count for a multi-piece plan.

Decision guide

Match a 40 Ft RV Sewer Hose Support to Your RV

By Support Plan

Because nothing here covers 40 feet alone, your plan for combining supports matters more than any single spec. Count the supports, the total length and the cost before choosing a pairing.

By Budget

Prices here are modest, but a long run multiplies them. Think in terms of the total spent to cover 40 feet, not the price of a single support.

About $80 for a full 40 feetKohree 20 Ft SupportTwo supports reach 40 feet end to end for $79.98.

Telescoping vs Accordion

The two supports use different mechanisms to span the same job. Knowing how each one works helps you decide which suits your setup routine and your storage space.

Telescoping

The Camco Sidewinder 15 Ft slides out from a compact body, so you pull it to the length you need and set it down. It compresses neatly for storage and deploys quickly, which suits owners who dump at every stop.

Accordion

The Kohree 20 Ft Support unfolds like an accordion and folds flat again. The polypropylene build bends to follow the ground, and the extra five feet of reach means fewer pieces on a long run.

Most buyers should default to the Kohree 20 Ft Support for the longest reach.

By Number of Supports

A 40 foot run can be covered with two or three supports, and each approach has different cost and storage consequences. Match the number of pieces to your bay space and how often you move.

PlanRecommended pickWhy it fits
Two supports for exactly 40 feetKohree 20 Ft SupportTwo 20 foot units meet the full distance with only one join to manage.
Two supports for about 35 feetCamco Sidewinder 15 FtA 15 foot telescoping unit plus a Kohree covers 35 feet with room to adjust.
Three supports for a winding routeCamco Sidewinder 15 FtShort telescoping pieces curve around obstacles and are easy to reposition.
Single support plus shorter hose runKohree 20 Ft SupportUse one 20 foot support at the low end and keep the rest of the hose short.

For Very Long Routes Specifically

Long routes make slope and alignment the real challenge. The aim is a continuous downhill line with no sags, steps or gaps where two supports meet.

Look for

Look for supports that can sit end to end with a continuous slope, plus a deep cradle that keeps the hose seated. Overlap the ends slightly, set each piece to the same angle and check that the hose runs downhill the whole way.

In this comparison

The Kohree 20 Ft Support and Camco Sidewinder 15 Ft can sit end to end, and the Kohree's height settings help match the angle across the join. Two Kohree supports give the cleanest 40 foot line.

When to Spend More

The difference between the two supports is only $10, so the decision is about convenience rather than money. Think about how often you set up and how much speed matters to you.

Spend more if

Spend more if you want a branded unit and fast deployment: the Camco Sidewinder 15 Ft extends in seconds and compresses well. It suits owners who dump often and want one quick piece beside the rig.

Save if

Save by using the Kohree 20 Ft Support. It costs $10 less, covers five more feet and reaches 40 feet in a matching pair, so the total spend is lower and there are fewer joins to line up.

FAQ

Before You Bring One Home

Is there a single 40 foot sewer hose support?

Not among these picks. The longest support in this group is rated for 20 feet, and the other is rated for 15. A 40 foot route needs two or three supports placed end to end, and two Kohree 20 foot units reach exactly 40 feet. Plan the number of pieces before you buy.

Can I use two supports together?

Yes, place them end to end so the cradles line up and the slope continues. A gap or step lets waste pool in the hose and invites a clog. Overlap the ends slightly, match the height of each piece, and test the line with a little water before you do a full dump.

What mistake costs owners the most on a long run?

Leaving a gap between two supports. The hose sags in that spot and collects waste, which is where clogs and leaks start. Overlap the ends slightly and run a hand along the top of the hose to check for dips. A single sag can undo the slope of the whole run.

Is a telescoping unit better than an accordion?

The Camco Sidewinder 15 Ft deploys faster and compresses neatly, but it is priced higher per foot. The Kohree 20 Ft Support covers more length for less money and folds flat. Choose by how often you dump: frequent dumpers value the quick setup, while long-stay owners care more about cost and reach.

How do I store two sewer hose supports?

Rinse both supports with a hose after use, let them dry, then fold or collapse them and strap them together. Store them in a bay or bin away from food items and drinking water gear. Keep them out of direct sun, since plastic and polypropylene can become brittle with long exposure.

What if my sewer inlet is far above or below my outlet?

Slope depends on the height difference as well as distance. If the inlet sits higher than your outlet, a hose cannot drain by gravity, and you may need to reposition the rig. If it is far below, the downhill drop can be steep, so use the supports to keep the hose from sliding.

Bottom line

The short version

A 40 foot sewer hose run needs more than one support, and the best plan with these picks is two Kohree 20 Ft supports, which reach exactly 40 feet for $79.98. The Kohree is the best base for a long run thanks to its longest reach, polypropylene build, deep cradle and lower price.

The Camco Sidewinder 15 Ft is the right add-on if you want a branded, quick-deploying telescoping piece beside the rig. Whichever you choose, keep a continuous downhill slope across every join, since a single sag is where long runs fail.
