I talked to a rep at Forest River today regarding attaching solar panels to the roof of the Roo. His position is that Forest River strongly recommends not attaching anything to the Roo's roof. I suppose this is the company line position they must take.
So, at this point, I'm not sure what to do.
I have considered attaching aluminum struts along the edges of the roof so that I would be screwing directly into the aluminum framing and not into the thin plywood roof. Then attach two struts across the roof where the panels would attach. This would place the weight and strain on the framing and not the roof. See image that I found (thanks Kevin):
Forest River could not recommend that either.
I suppose another option is to just mount the panels to a stand and set them out when I get to where I'm going... big hassle.
Any thoughts, ideas or input is very welcome.
