What is inside those walls?

[riven1950]

I need to mount something on the interior of an outside wall of my 2007 Aerolite 718fd. Not very heavy, just a shelf, maybe 5lbs or so. Will be holding electronics so no sticky tape kind of crap, it needs to stay up.

Wondering if the wall is filled with foam or whatever. I know the interior walls are open like a mobile home, fabric covered paneling. Have some butterfly toggle hangers that will work if it is open but I am thinking there would be foam in the outside walls.

Anyone know? Will post on Aerolite forum also.

Thanks

I'd use a stud sensor to find the studs and mount to those if possible. I know the winter package includes foamed wall cavities. Probably all models do as the foam gives rigidity to the walls. Look at your dinette seat panels. Mine are made from the window cutouts and show a good cross-section of what your walls look like.
