Anyone have experience washing RVs? We washed about 30 yesterday for a new client to prep them for a show. Took ages. Had to brush really hard to get the black streaks off, especially on the metal sided ones. The owner was happy though and wants us to wash his entire lot of 160+ campers every month. Of course I want to figure out a way to do this without brushing because, well that would suck and take way too long.
Any advice would be great. I’ve thought about trying to just softwash them like a house but that seems like it could be disastrous.
