I wash fully setup. Then I use to quality cleaner was (Meguires) on the camper. I do the side walls by folding one in at a time and working in the tight space inside to reach all the spots.
After that I lower both walls, and fold the roof. I use a wad of cloths/towels to prop the front roof panel up and get the top portion of the rear panel, then fully fold down and get the rest. I use a ladder to avoid having to crawl on the roof panels.
Lots of stretching to get the roof panels done.
Last is the lower sides.
I don't see the need to wax more than once every 3-4 years as I keep my camper in the garage when not in use.
