On my MH... the slinky was in a garbage bag. The white hose was stuffed into the same compartment (where the electric cord/box is.) I was not comfortable with that... the water (white) hose was pretty dirty, old and I was afraid it would bust under pressure, so I bought a new blue hose. I put it inside the MH behind a chair. I was thinking of making a place for the slinky by attaching a PVC pipe with end fittings to my rear bumper. (Nope... no place there already) I would have to go beneath the bumper due to the spare tire's placement. Thought about making it vertical then realized I'd have to lift the stinky slinky over my head level risking an icky shower incident....
