RV Sewer Hose Support for Uneven Ground, Gravel & Sloped Campsites
Accordion supports assume the ground is flat. Campgrounds didn’t get the memo. Here’s why waste pools in your hose on real-world sites, and how to get a clean downhill run on any terrain.
Drainage needs continuous fall
Waste water only flows downhill. For a sewer hose to empty completely, every foot of it needs to sit lower than the foot before it — one low spot and waste pools there, sits between dumps, and becomes the smell you can’t find. A support’s entire job is to create that continuous fall from your outlet to the sewer connection. Ground-based supports can only do that job when the ground already slopes the right way.
What each terrain does to a ground-based support
Gravel pads
Accordion feet settle unevenly into loose gravel, tilting segments and creating dips. Every time you walk past or the wind gusts, it settles a little differently.
Grass & soft ground
Supports sink where the ground is soft, mowing crews have to work around them, and a week of rain turns the footprint into ruts that hold the hose low.
Ruts & potholes
A ground support bridges nothing. It drops into every hole, and the hose follows. Each dip is a pocket where waste collects and sits.
Site slopes toward your RV
The worst case. The built-in taper on accordion supports (a few inches over 15 feet) can’t overcome ground falling the other direction. Waste runs back toward the outlet.
Long distance to the hookup
The farther the run, the more terrain variety it crosses, and the more chances a ground support has to create a low spot along the way.
Curbs & height drops
Sewer connections below grade or across a curb create a sudden elevation change that rigid segmented supports handle awkwardly, if at all.
Take the ground out of the equation
Any ground-based support
- Shape of the support = shape of the ground
- Slope only works on cooperative sites
- Hose exposed to sun and weather all stay
- More terrain = more failure points
Levitator suspended tension line
- Hose hangs in the air between your outlet and the hookup — terrain underneath is irrelevant
- You set the fall once with the tension line; gravel, ruts, and slope can’t change it
- Included UV sleeve shields the hose the whole stay
- Same 2-minute setup on every site, every time

One support for every site you’ll ever park on
The Levitator was designed by a full-time RVer after 8 seasons of fighting exactly these campsites. It was featured in RVBusiness for a reason: it’s the only support whose drainage doesn’t depend on the ground.

Common questions
What is the best RV sewer hose support for uneven ground?
A suspended support. Ground-based accordion supports mirror the terrain they sit on, so uneven ground becomes an uneven hose. The Levitator suspends the hose from a tension line anchored at both ends, keeping a continuous downhill run regardless of what’s underneath.
Can I make an accordion support work on a sloped site?
Sometimes, with shims, blocks, and patience — and it needs redoing every time the ground shifts or you re-park. If the site slopes toward your RV, the accordion’s few inches of built-in taper usually can’t overcome it.
Does gravel really affect sewer hose drainage?
Yes, indirectly. Gravel lets support feet settle unevenly, which tilts segments and creates low spots in the hose where waste pools between dumps. That standing waste is the usual source of sewer odor at the campsite.
How does the Levitator attach on a site with no structures?
It anchors to your RV’s outlet area on one end and at the sewer connection on the other — the two points every hookup site has by definition. No trees, posts, or extra hardware needed.
