Does anyone have experience with allowing an RV dealership to wash your roof. I'm unable to get on even a step stool due to knee issues, and age. I seen posts about the dangers of creating minor damage, that will cause leaks, due to things like a pebble stuck in the shoe sole, stepping on seams, and other risks.

For me part of washing my roof is doing a inspection for any potential problems. By having a dealer do it, one would assume they would be qualified to wash it and inspect it for you. FWIW If I was unable to do it, I would take it to the dealer to do it for me.
