I like the Rhino the best. We carry a 10' and a 15'. I only use them when setup on a FH site, which is not something we do very often. One of the features I like is that those 25' of hoses fit into a carrier that is the width of the trailer, because they collapse so well and stay collapsed.
I also carry the cheap blue slinky, and use that at roadside dump stations. I find it is just easier to work with, and the features of the Rhino aren't needed for a dump-and-go.
And for the last few months, been dumping at home using the Sewer Solution. I could get rid of the cheap blue slinky, since home dumping has become favored over roadside dump-and-go. But it is rolled up in a 5gal bucket and doesn't take up much space, so it will probably just keep going along for the ride.
