I can't figure out the purpose of the two rings that fit inside the hose ends. Is I insert them, the twist-lock fitting and the outlet fitting will not fit. Do I just dispense with the inner rings, clamping the hose directly on the twist-lock fitting and outlet fitting? If all this material were anything other than plastic I would do it without concern.
Dealers do goofy stuff.
I've tried pretty much all the setups on the market at one point or another because we use a combination of full-hookup sites, dump stations, hauling wastewater away from boondocking sites in tanks, home "dump stations" that involve an uphill run, etc.
There are several key points that have emerged over the years:
1) If you are dumping at a dump station, then a 10' high-quality standard vinyl hose with a bayonet connector for the trailer end, and nothing on the other end, works best. High quality hoses are thicker and will last longer. Extra length or connectors just get in the way in this situation.
2) At full-hookup sites you need a different hose. A 20' high-quality standard vinyl hose works best, with bayonet connectors on both ends, one of them with a swivel. You also need a matching elbow that has the stepped threads for various size connections.
3) At some full hookup sites it's best to just hook up a greywater hose. Garden hose with the necessary adapters works well for this. This is more convenient for longer distances and also for situations where there is a good deal of foot traffic, since a 3" vinyl sewer hose will be damaged if stepped on while a garden hose will not
4) Fancy setups like the Rhinoflex work OK but the way they are priced and sold it is not practical to replace only the hose when it gets damaged as it inevitably will at some point. The ends and clamps will outlast many hoses
5) Sewer solution is fine for situations where you have to dump uphill and I have one for that purpose but I have found it to be a nuisance for general use. A standard 3" hose is faster at a dump station, some dump stations don't have pressurized water, etc.
