What do most folks here do when mounting something to their camper walls? Toilet paper holder, towel bar, pictures, etc? I feel like the screws supplied with most of these things would just go right through the wall. I don't actually even know what the thickness is on the interior and exterior "walls." Does not feel very thick. Double sided tape? velcro? Smalls screws?

Does not feel very thick. Double sided tape? velcro? Smalls screws?For light things I use adhesive backed hooks, small stuff gets moved all the time anyway ....The towel rack I bought one that slings over the top of the bathroom door.For couple of things I have used very coarse screws just shorter than the thickness of the wall, which seems to have held up to moderate abuse.

Sometimes it helps to see what the RV builder used to mount stuff to the wall.For towel bars, I made up some small spreader plates of thin (1/4" or so) plywood, looking vaguely like blank switchplates for lights switches, glued them to the wall (mainly to keep them in place while working), and then used plastic wall anchors through both the plate and the luan of the wall. My theory was that they would help spread the force of the mount out a bit and so prevent puncturing the wall, and the added thickness would make the wall anchors more likely to hold. Thus far it's worked out okay.For many things, command strips would work nicely and be removable if desired.

If my project needs a lot of support, I use plastic spiral wall anchors. You pre-drill a hole and install the anchor, and then the screw goes into the anchor. If you have foam inside the wall, the anchor can provide a lot of support by spreading the load.One tip -- don't drill in too far, and make sure that the wall anchor is shorter than the distance between the inside of the wall and the exterior of the RV.Please do not ask how I learned this tip.

TNGW, that works well if the wall is hollow. But on most newer RVs, the void is full of high density foam. Not sure if the toggle would deploy in the foam??

I tried rivets, but they just pulled right through the thin wall, I think they are really intended for sheet metal. I finally found the smallest toggle bolt I could and it works great! http://a.co/h0EzL2R
At least in my bottom of the line RV there is no foam in the interior walls, so no issues.

Did you use an RV Oscar rivet tho? An ordinary "pop" rivet will not work unless you can get behind the wall surface and put a washer on the rivet first. An Oscar rivet has high holding strength and you normally shouldn't be able to pull one out through 1/8" luan plywood.
