How to mount to thin walls?

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?

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.
