Winnebago's Thermo-Panel Construction "Panel Replacement" ?

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.

My sons wood shop in high school made some structures that needed vacuum bagged. they made them out of heavy plastic sheet and duct tape. then used the vacuum from a shop vac. it worked for them but, the panels weren't  very large.

the industry is all about vacuum bonding now. vacuum bonding does seem feasible with a vacuum pump and a way to secure some tarp appliance over a slab floor with a roof panel inside. but a crown would be much more difficult. i thought about a 1x3 chunk of oak like a exposed beam but laid flat. construction adhesive then jack into place so that you get a crown. let it set and voila....or maybe no if you did could run a 4x6 lengthwise to support all till set. just set them to clear the AC. thats my brainstorm...hehe

On my old 72 chiefton I used 2x2 and tpaered the ends to resemble a truss. I made to roof supports and installed then at 16" centers to adjoing 16" on center wall studs. It put a 1/4 in rise in the center and snow and rain rain off the sides with no *lakes on the roof. As far as thermo bonding. I've always podered the same thing as if was doable and cost worthy to do as a D.I.Y. guy.
