30 years RVing, and I've always used the cheap hoses without any problems/leaks, etc. But the other day I finally decided to break down and get a better hose.
I purchased this Valtera Dominator.Two 10' sections, a clear 90 degree fitting for the dump, plus 4 drip caps. The great thing about this hose is that it "clicks" to expand/contract/turn, and then holds/maintains it's shape (think of an oversized bendy-straw). No more "self expanding" squiggly hose when you pull the valve open! Each section collapses down to just over 3', and STAYS at 3'! I haven't had it long, but the few times I've used it so far, I'm extremely happy with it.
