The Dominator kit (D04-0275) is the other complete kit worth putting next to RhinoFLEX. Two 10-foot hoses, fittings that rotate so the hose can lie flat, a clear 90-degree adapter, four drip caps. The listing's storage number matches Camco's: 39 inches collapsed. The wall thickness it prints is also 23 mil.
People who have used both tend to talk about the fitting bulk, not the hose wall. A tighter hose bay sometimes accepts the Dominator end when a larger swivel will not. We are not going to pretend we measured both fittings with calipers. If your bay is the problem, look at the end cap in the listing photos against the opening you have, and buy the one that goes in without a hammer.
The clear adapter is the same idea as Camco's clear elbow: you watch the flow finish. The listing does not describe a 4-in-1 dump fitting in the words we read, so if your dump inlet is an odd thread, check the adapter before you leave the driveway. A hose that is perfect and an adapter that doesn't thread is a long walk.
Same honesty rule as the Camco kit. We ranked it a hair under RhinoFLEX because the Camco kit's listing spells out the 4-in-1 inlet range and because that kit is the one we would hand a first-time owner. Dominator is the right pick when you already know a bulky fitting will not fit your bay.

Works in its favor
- Rotating fittings and a clear 90-degree adapter
- Collapses to 39 inches per the listing
- Same 20-foot, two-section layout as the Camco kit, so extensions are easy to reason about
Holds it back
- The listing we read does not spell out a 4-in-1 inlet adapter
- Still a joined hose: one extra seal versus a single length
- Will hold a sag without a support, same as any wire-reinforced hose

Questions worth answering first
Are Dominator and RhinoFLEX fittings interchangeable?
Both use the common RV bayonet. A Dominator hose will usually lock onto a Camco elbow and the other way around. Gaskets still have to be the right one, seated flat, and not doubled up.
