Camco RhinoFLEX 20ft
The RhinoFLEX is the hose I recommend to every new RVer. It comes with both a clear elbow fitting and a translucent inline fitting so you can see when the tank is running clear. The accordion design is rigid enough not to kink and flexes enough to store in a 4-inch bumper tube. After two years of constant use mine still seals cleanly.
I have dumped tanks at hundreds of campgrounds and learned which RV waste hoses survive abuse. Here are the five I would actually buy this year.
I have lived in my RV for six years and dumped my tanks more times than I can count. A good waste hose is the unglamorous piece of gear that separates a clean dump from a horror story. Here are the five I would actually buy in 2026, based on what has survived freeze, sun, and gas station gravel.

Camco RhinoFLEX 20ft
The RhinoFLEX is the hose I recommend to every new RVer. It comes with both a clear elbow fitting and a translucent inline fitting so you can see when the tank is running clear. The accordion design is rigid enough not to kink and flexes enough to store in a 4-inch bumper tube. After two years of constant use mine still seals cleanly.
Valterra Dominator
A heavier-duty hose for full-timers and frequent travelers. The reinforced vinyl is noticeably thicker than budget options, and the fittings are made from a tougher composite. I have driven over mine accidentally and it survived without splitting.
Thetford Titan
The Titan uses a triple-layer construction that holds shape in freezing temperatures. If you camp in shoulder seasons or boondock at altitude, this is the one. Pricier than the Camco but worth it where temperatures dip below 25 degrees Fahrenheit.
Camco RhinoExtreme
The Extreme version uses a thicker 23-mil polyolefin and metal swivel rings on the fittings. For long-term setups where the hose stays connected for weeks, this resists UV degradation better than thinner options.
Lippert Waste Master
The Waste Master is a premium hose with a permanently attached cam-lock fitting that requires no separate parts. It is the cleanest dump experience I have used, but it costs significantly more than the alternatives. Worth it if you hate handling messy fittings.
Common questions
20 feet is the standard length that covers most campground dump stations. Some sites place the sewer connection farther from your rig, so I recommend carrying an extension or buying a 20-foot kit with extra fittings.
Yes, but only if you have a proper rigid or semi-rigid hose and you keep the black tank valve closed until ready to dump. Leaving the gray tank open for sinks and showers is fine.
