Not a lot to update. We are working some on the inside and have installed the interior walls/frame for the bathroom. I will get some pics of that soon.
I visited the Rhino coating place and was not impressed with their operation. The bay they used, which they claimed was 14 feet high was only 11'10". Our camper would sit at 12 feet on the flatbed. Just didn't get a good vibe in general.
We then thought about the liquid rubber epdm roof but after calling the manufacturer we were told a very big NO that it is not for new installations, just for skim coating old worn rubber roofs.
I am back to the aluminum roof, which was probably the best choice to begin with, as the rest of the camper is aluminum (steel frame). I have found a local truck repair place that will sell a 103" wide 0.040" thick aluminum roof coil for about $15 a linear foot. A bit thicker than I was planning but I think we can work it. Small branches would then be a non-issue.
I think we would mostly float the roof even though we do not have any top vents or structures to tie it down. I would Sikaflex 252 bond it for about 2 or 3 inches to the plywood around the top of the roof, then after that dries, I would fold over the aluminum and Sikaflex 252 bond the 1.5" fold to the aluminum siding. I could probably pull my boat with 20 square inches of aluminum to aluminum bond of Sikaflex 252. The main center part of the aluminum roof would be free to buckle in the sun and the Sikaflex on the edges I think has enough flex that it would stay bonded.
So the only little thing to decide is what to use on the floating part between the plywood roof structure and the aluminum roof skin. I am also wondering if I should paint the plywood with some sort of exterior grade paint first or if that is not needed.
