Buy the Camco RhinoFLEX 20-ft kit ($79.99) unless bayonet fittings have personally wronged you, in which case the Lippert Waste Master's cam-lock connector is worth its roughly $217 price. Scores weigh published specs, warranty, and price. We have not lab-tested these units.

Lippert#2 PickWaste Master 20' Hose Kit with Cam Lock (359724)
What actually matters in a sewer hose
Three things: the fittings, the kit contents, and whether the hose survives storage. Length mostly does not; every kit here is 20 feet, shipped as two 10-foot sections (the Waste Master is one 20-foot run), and you use one section when the drain is close.
The fittings are where dumping goes right or wrong. Four of these five kits use bayonet fittings, the twist-on lugs that mate with the RV's outlet. The good versions swivel so the fitting turns without twisting the whole hose; the RhinoFLEX, RhinoEXTREME, and Dominator all do this. The adapter on the other end matters just as much: Camco's 4-in-1 and Thetford's Revolve 5-in-1 both cover the 3-inch slip and 3, 3.5, and 4-inch threaded inlets you meet at dump stations, so either kit connects nearly anywhere.
Kit contents separate a complete purchase from a start. The RhinoFLEX box has hoses, a transparent elbow, the adapter, and storage caps. The Titan adds two replacement seals, the part that fails first. The Dominator lists two hoses and an adapter, and that is it.
The cam-lock case
The Waste Master replaces the bayonet ritual with an industrial cam-lock: push it on, close two levers, done. It adds a 90-degree nozzle with a shut-off valve and a clear view port, so you can watch the flow finish and close the hose before you disconnect. Those three features address the exact moments people learn to hate.
The premium is real. Lippert's own page would not render a price when we checked; search attribution puts it around $217 list, roughly triple the RhinoFLEX. It also compresses to 5.5 feet rather than collapsing flat, so it wants a longer storage bay, and the matching 20-foot extension costs $294.95, more than the kit. If you dump weekly as a full-timer, the math can still work. If you dump five times a summer, it probably does not.
When the cheap hose is fine
If you camp a few weekends a season, dump at well-kept stations, and store the hose in a bumper or bay, the $79.99 RhinoFLEX is not a compromise, it is the correct answer. The failure modes the expensive hoses guard against, abrasion from gravel pads, getting stepped on, daily connect cycles, mostly do not apply to occasional use. Spend the difference on leveling blocks.
The RhinoEXTREME's case is narrow but honest: same kit design, tougher jacket, $33 more. Camco claims it will not dent, rust, or crush if stepped on. We note those claims come from Camco's marketing pages, not the thin product listing, and we could not verify a warranty term for it.

The two you have to price yourself
Valterra and Thetford publish no prices. Both sell through retailers, so the Dominator and the Titan cost whatever the listing in front of you says, and neither states a warranty term on its product page. That does not make them bad hoses. The Dominator's position-holding coil and 39-inch collapse are useful, and the Titan's TPE construction carries an extreme-temperature claim plus those spare seals. But we cannot call something a good value when the maker will not say what it costs, so both rank below the kits with published prices.
What we would skip
Nothing here is junk. But we would not pay the RhinoEXTREME premium without a confirmed warranty, and we would not buy the Dominator or Titan without comparing at least two retailer prices first, since dealer spreads on unlisted-price gear can be wide. And whatever hose you buy, buy a kit with an adapter. A bare hose that cannot connect to the dump station inlet is a story you only need once.
