thanks guys.
the bolt at the top that goes through the camper wall is just a 1/4" stainless bolt with about an 1.5" washer on the interior side. the bolt just barely missed a interior framing piece so the washer spreads some of the forces over to it. with tons of sikaflex in and around the hole on the outside. the bottom two bolts were nearly stout enough for the whole thing on its own, so the top bolt was just to keep it from rattleing around more then really hold it there.
