Has Anyone ever done their own Duplication of the Thermo-Panels used by Winnebago in their first RV'S?. Other than the heat, pressing. It would seem possible to fabricate close to the original.
And as I have a Roof that has structural sagging. I Chose not to just brace up the panels and just add
an additional layer of thin, structural plywood. Or 3/4 inch T&G. I have found a company that make newer stuff for trailers. But I would like to save the cost (if feasible) by fabricating then myself.
