I totally agree with Barb. We got one of the towel racks that hang over a door and put rubber bumpers and silicone on the parts that would scratch the door if it rubbed. That keeps two bath sheets, two hand towels, and two wash cloths in place even while on the road. We also have the stand alone TP holder that holds up to 4 rolls. The shelf over the toilet holds shampoo bottles etc. that we don't want to leave in the shower while on the road. We also started using the disposable hand towels advertised by Kleenex for some things including some of the cleaning, so they go up there too. I keep a couple of the small plastic "crates" under the sink to keep cleaning supplies organized in one and toilet chemicals/calgon/dishwashing liquid (for the black tank) in the other. We don't use the actual chemicals very often, but the calgon/dish detergent is used all the time.
It takes a little time to get things fixed and figured out the way you want them, but it will all work out once you can start using the trailer. I know you are waiting for it to come in and the waiting is hard which leads to lots more questions and worries. Hang in there and we'll all help where we can. lol
