What to use for new wall paneling

[rppngears]

Hi, I am redoing the walls and ceiling in a toy hauler I just purchased and can't find any conclusive info on what to use. The options I've found with are

1. Vinyl covered LUAN - Seems fragile, but minimal thermal expansion
2. FRP covered LUAN - Seems a bit more durable
3. FRP sheets - Thermal cycling seems to lead to wavy walls
4. Filon - Good thermal expansion but I don't really understand this one. Seems to come in rolls. Can I just glue it to the plywood walls?

That info is just what I've gathered from research, please let me know if anyone has info that contradicts it.

Looking for any help, suggestions, or general info on what materials are best for durability and appearance.

Thanks!

I have installed thousands of sheets of 3/32 inch FRP in every situation from commercial bakeries cold storage units to outdoor car wash bays.
It should be applied with a full glued back over 1/2 inch (or more) plywood.
It is extremely durable bright white, cleanable and has trims to make a very attractive installion.
We used to put 8 ft high 45 foot rolls in refrigerated semi trailers.
Great stuff.

YES ! While designed for exteriors there is no reason is ca not be used on an interior.

Most manufacturers use a spray adhesive (like 3M 77 or 99) or a heat activated "dry" adhesive. Most people really like the fact that it is a continuous roll with no seams.

The prudent thing to do is to ask the wife what she wants.

Have you looked into corrugated metal roofing? I've seen some of that stuff falling off a roof and it looks pretty lightweight. screw it on, comes in different colors. Maybe even find it used.
