Since I'm waiting for my trailer parts to arrive, I'm working on design and layout. Since I live in MN and where most of my camping is done, I'm considering a 3-layer wall.

The outside I assume will be plywood of some sort, then a layer of insulation and then the interior wall. For my interior walls, instead of being blank, I plan on "wallpapering" with maps and atlas pages. What would be a good thin material for something like this? And I would probably do the wallpapering before putting the walls up....

Thank you for your thoughts and ideas...

Titebond II and canvas (PMF) if all you need is to cover the foam.

I used painters drop cloth canvas for harbor freight.

I have been involved with a lot of stressed skin panels - either foam or honeycomb or wood stingers between the skins. I've learned to go to great lengths to be sure the skins are balanced. On occasion when they have not been, the bow from humidity and or temperature changes. Early on I had one with 3/16 ply on either side and plastic laminate on just one. Bowed like crazy when it got humid. Now always but plastic laminate (backer) on back side. It may not happen to you but just a consideration.

1/8" baltic birch inside & outside, with 3/4" in the middle which provides hard points for attachments & foam inserts for insulation worked for us. It's strong, light & stiff. We did cover with aluminum skins, just for durability. Tried & true, easy to build & strong. Materials are readily available.

Doing this provides interior space to run electrical wires for lights, switches and power outlets. I favor fiberglassing the exterior plywood, then painting it to protect the fiberglass from UV damage, instead of using exterior aluminum sheets. Fiberglass weighs considerably less and provides for superior quality water proofing.
