2 Best 40 Ft RV Sewer Hose Support in 2026: A Practical RV Guide
Forty foot sewer hose support planning, with no 40 foot rated support listed, so this guide compares the closest 15 and 20 foot supports for long runs.
By Hardcastle's RV Editors
10 min read2 products evaluated
No 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 hose run is a big span, and each support's nominal length is a ceiling.
Two supports are compared: a telescoping Camco Sidewinder rated for 15 feet and a polypropylene Kohree accordion for 20 feet. Each is described by its stated length, material and storage.

What Matters Before You Choose a 40 Ft RV Sewer Hose Support
Key buying criteria so you get the right fit the first time.
Rated length
A 40 foot route needs more than one support, since the longest one here is rated for 20 feet. Count how many supports it takes to cover the whole run. Measure the route from the outlet to the sewer inlet.
Continuity of slope
When two supports meet, the slope must carry across the join. A step or gap collects waste in the hose. Set both supports to the same angle and overlap the ends.
Build type
Telescoping and accordion supports differ in setup speed and cost. A telescoping unit slides out, while an accordion unfolds. Choose by how often you dump.
Storage for several supports
Two or three supports take real room in a bay. Check the folded size on each listing. Plan the space before you buy.
Stability on a long run
A long run is heavier when full and tips more easily. A wide base and a deep cradle help. Look at the cradle description for each support.

Before You Bring One Home
Is there a 40 foot support?
Not among these picks. The longest support listed 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.
Can I use two supports together?
Place them end to end so the cradles line up and the slope continues. A gap or step lets waste pool in the hose. Test with a little water before you dump.
What mistake costs the most?
Leaving a gap between two supports. The hose sags there and collects waste, which is where clogs start. Overlap the ends slightly.
Is a telescoping unit better than an accordion?
The Camco Sidewinder 15 Ft deploys faster and compresses neatly, but it costs more per foot. The Kohree 20 Ft Support covers more length for less money. Choose by how often you dump.
How do I store two supports?
Rinse both, fold or collapse them and strap them together. Store them in a bay or bin away from food items. Keep them out of direct sun.
