RhinoFLEX or Dominator: two 20-foot kits, one real difference

Start with the Camco RhinoFLEX kit. The listing spells out a 4-in-1 adapter for the inlet sizes you are likely to meet. Move to the Valterra Dominator if you already know a bulky swivel will not go into your hose compartment. Don't expect the hose wall to be the thing that separates them.

The adapter is the Camco argument
Dump inlets are not one pipe. Camco's listing says the 4-in-1 handles a 3-inch slip and 3-, 3.5-, and 4-inch threads. That is the sentence that makes this the first kit. Valterra's listing, in the text we could verify, describes a clear 90 and rotating fittings and does not walk through that same inlet range. If your home park uses one friendly fitting, you may never care. The first time you meet a different thread, you will.
The bay is the Valterra argument
RhinoFLEX ends are not small. Owners with a shallow hose bay sometimes cannot get the swivel through the door they have. Dominator's reputation, among people who have used both, is a more compact end. We did not caliper the two fittings. If the compartment is the constraint, compare the end in the product photos with the opening, or buy Dominator and keep the receipt.
What you still have to add
A support. Both hoses hold a bend, which means both will hold a sag. A Sidewinder sized for 20 feet is the matching piece. Slack at the bayonet, from the length calculator, matters more than the logo on the cuff. And neither elbow is promised to fit in the OUTPRIZE or Lyrivan storage tube.
Questions worth answering first
Can I join a Camco hose to a Valterra elbow?
Usually yes. Both use the common bayonet. The gasket has to be the right one, seated flat, and the fitting has to turn without side load.
