Well I picked up the Rhino Flex today and used it for the first time at home to flush the black tank with the flush system. I have to say I really like it so far. Outside of the fact that I don't think the fittings were put on as far as they could have been out of the box (I put them on better) I like the way it collapses and stays that way. Takes up a lot less room in my compartment and much easier to put away. I also liked that when I disconnected it from the RV and started collapsing it toward the drain that the residual water was forced out of it better than my old hose. I also like the caps that come with it to cap it off on both ends.
Thanks for the input everyone.
