Ok, So I got up on the roof today to sweep off the Ash from a distant Fire blowing Ash into Santa Barbara. What I discovered is a Rough Surface top , which has no seams, nor rivets, except at the front and back where the Fiberglass Caps meet. Can you all give me some insight .... Is it OK to be up there, to wash and maintain or not. It seemed a little soft in places with crossmembers every 30 inches or so for solid support . My Country Coach felt more firm. Also, I was told by Troy at Liberty the Top was Metal, and it expands and contracts during the day and makes some snapping noise. I am assuming this is normal.
