I am eyeballing my new slide-in camper, and am wondering what the white interior wall skin is made of, and more importantly, what is a good modern, moisture proof replacement?

Also, would rigid foam board insulation be a better choice when replacing the insulation?

Thanks. Hal

I don't necessarily know if foam is better, but I repaced all the old fiberglass insulation with the blue blocks.

The original wallboard in mine was like a carboard covered with a vinyl. I used Luann panels, coated them both sides with urethane & then I will use a vinyl.

I used the FRP below in my shower stall.
