Anyone interested in 83 Pace Arrow Tear down and Rebuild?

By the way, does anyone have a good, easy, quick, cheap, way of building a scaffold for temporary use to get up on the roof of an rv to work on the roof?

This is for a 36' 5th wheel, which probably needs the roof, (tpo/rubber) replaced. I'll need to be working from both the sides and the top of the roof.

I think the roof is about 11'6" high, and about 12'6" with the ac.

Nothing like asking for the impossible, is there?
