What can I mount on my laminated wall?
Hi, I have a new Creekside 20FQ travel trailer. It has 2" aluminum laminated walls. I built a set of shelves to put in the bathroom for additional storage. Now I need to mount it on the wall. My q...

What sorts of weights are you envisioning this shelf carrying? Obviously anchoring strategies for lightweight stuff are going to be quite different from those for heavy stuff.
For some towel bars in my motorhome (in this case attached to the interior walls, so no foam core on the inside), I made up some little backer plates of thin 1/8" (probably actually 5mm) plywood to go under the mounting feet. These backer plates I pre-drilled to fit the standard plastic wall anchors that came with the towel bars. I then glued the backer plates onto the wallpaper (mostly to hold them in place while assembling everything else), drilled through the holes in the backer plates through the luan wall surface, and ponded in the wall anchors and mounted the towel bars as usual.
My idea is that the backer plates do two things: they provide a thick enough skin for the anchors to properly grip, and they help to spread out the forces of the mounting feet to avoid possibly puncturing or ripping the wall paneling. So far (which isn't all that long, admittedly), they've held up just fine.
Maybe something like that would work for you. Using the plastic anchors rather than molly bolts or winged anchors will avoid damaging too much of the foam core.
