Looking for some help on finding the material that is behind the filon in the underhung area around pin box and front storage compartment. I pulled off the filon and what apears to be some sort of cardboard material? It has a paper over the cardboard type material and this is behind the filon. I have found the filon to purchase to put back on, but not having any luck with what is behind the filon. I have an 08 Bighorn that experienced a frame chassis issue under the bedroom floor that I am repairing. Any help from the group is greatly appreciated. Here is a picture that you can kind of see the material I am asking about.
