As far as I know its filon/styrofoam/luan/wallpaper. My thought was to get it apart, scrape off the styrofoam and glue on the harder blue styrofoam then maybe laminate that to protect it. Original filon would stay as the outside skin.
I do like the diamond plate idea. On my to hauler I think the inside of the door was an abs skin not luan
That looks workable to me. From experience I can tell you that construction cement, the Liquid Nail type stuff, works well with insulation board. I've seen some thin insulation board in the big box stores that looks harder than the foam stuff. Maybe a couple of layers of that laminated on.
