In regards to doubling up the square tubes to increase surface area I am in complete agreement. So much so that if you look at the photo closely you'll notice just that. I doubled up to increase the surface area ;-) for the adhesive.

My main concern about the through bolting is that your solar panel is fairly heavy and mounted behind the trailer axle. When the TrailManor goes down the road, everything behind the axle has upward AND downward thrust, like a whip. The pressure of the downward thrust will be lessened by the 3M4200 sealant that you used. However, the upward thrust will pull the bolt and backing plate up against the roof panel. The combination of the 2 will most certainly cause the styrofoam between the inner and outer skin to compress if you do not have a crush sleeve in there.
