Well, I'm not a Rhino user, but I've never had any serious issues with any of my cheap-o .7 mill brown hoses. I have 7 ten foot lengths and use them in a variety of ways. One is dedicated for use at dump stations, but also gets used when parked for several days, when we have full hook-up sites.
The reason I have so many is because I have 2 sets of valves, spaced about 20 feet apart. I can connect both valves using a Y adaptor and don't have to switch hoses if parked for several days.
Also, we move a lot, and no 2 campsites are ever the same. I want to make sure I have enough hose to reach any location.
Another reason for so many, they last about 2-3 years before starting to get pin-holes. I actually have them on a "purchase new hoses" rotation schedule. Every year, I pick up at least one new hose (usually 2 of them) and toss out the most used one, especially if they spring leaks or get pin holes.
For me, this works.
One trick I always do with my hoses when storing them, is to collapse them tight and put the caps back on. They take up less space that way.
I store them in a plastic foot locker purchased from Wal Mart.
I am now using this grey one at home to transport from the camper to my septic tank via my blue tote. It's permanently located at my septic tank now.

I guess what I'm saying is; Yes, Rhino is probably the best, but used carefully, don't drag them on the ground, and the cheaper ones work just as well and hold up for some time.
