I like the newer Rhino two section 20’ hose. One 10’ is all I have needed so far at a dump station. What I like is it stretches out to what you need without pulling back. I have stretched one to almost its max. Then it did pull back some.
I have used the same Sidewinder since 2006. I have read where people do not see its use. I like to think a straight run to the glory hole in the ground will keep solids moving in the right direction during the gray water dump. Just me….
Two things about the Sidewinder. I only attach it to the Rhino at the beginning and the end of the Rhino because the hose is straight to the hole. No need for other hold down points. Gravity is wonderful. I anticipate how much the hose will flex under pressure at the beginning of the dump and that sag point is where I latch the high side of Sidewinder to.
