There are a few ribs in mine that have strips of the aluminum skin material riveted to them as shims. Clearly, the original builders wanted an even surface along the ribs to avoid deformation of the inner skin once installed.

Michael, thanks for your reply. I'll just start drilling rivets and pulling off panels. What could possibly go wrong...
I think your use of bed liner material on the exterior should be an interesting look - sort of a stealth Avion. I've decided to buy a large can of the Kool Seal elastomeric roof coating, put two coats on the roof and at least one coat on the entire inside of the shell before I put the insulation in.
And I am now thinking to glue 1/2" sheets of foil faced R Max polyisocyanurate insulation board (widely available, at HD and most other building supply stores) in three layers into the shell, using contact cement to bond the layers. Then sandwich everything in snugly with the inner skin. That board has the highest R value of anything on the market, even exceeding foamed-in closed cell foam. I reckon to get nearly R10 with that lay-up.
What I've learned crawling around on top and from the panels I have already removed inside is that the foamed-in factory insulation was pretty erratic in its depth and coverage - voids and thin spots in many places. The board glue-up will eliminate that and be a lot easier to apply uniformly, I think. Plus I have to think that the three layers of foil will add some extra pizazz to the final R value. I figure to seal any nooks and crannies with the little cans of spray foam.
i will put 1/16" x 3/4" bedding tape on the inner faces of the ribs before riveting on the inner skin, to address the thermal transfer issue you raised last spring.
Thanks again for your reply. Isn't it interesting how we each find our own solutions to the challenges these old Avions present us with!

Interesting approach for the insulation do you think there will be any concerns with the ridgid foam squeeking from movement ? Do you think contact cement will hold ? I believe Avion thought that the application of spray foam not only insulated but also helped with structural rigidity. I would think modern closed cell spray foam is superior to what was used in the 60's for insulation and strength but I could be wrong. I'm not sure what direction I will take with mine but your idea is interesting. Will the 1/2 " ridgid foam curve without having to make back cuts ?

Howdy!
Happy belated turkeyday!
Tiki I really like your flatbed rig, lots of storage.
What are those poles between the cab and camper
for?

Michael111, tomorrow I will begin drilling out the rivets and removing the inner vinyl-coated skin and old foam in my C11. I'm wondering if you have replaced the foam and the inner skin on your rig yet? And resolved the Luan/ rib insulation idea you proposed. I'd like to learn what you've learned...
