Good point. We too went the wire basket thingy on the floor route, but it drove me nuts finally. We have the 291RLS, with a small toilet room, and I was concerned about hitting wires, plumbing, etc, so I ended up mounting fairly high on the wall, which backs up to the sink - figured plumbing would be up above the sink, and its away from the switch on the back of the wall.
So, so far no leaks from that or shorts in the wiring.
One of the problems with the wire basket, is you had to store it to tow the RV, or it just rolled around, and with TP all over. I am considering using some of the self-adhesive wiring hooks, to stick on the wall, and then part of the wire basket in the wire loop part, to eliminate the moving.
Never know when you'll have a blow out and need that extra roll of TP.
