But then when the dampness disappeared with the new materials it was proven to be condensation. You might try glueing roll out heat reflective sheeting to the panels.

I absolutely don’t think plastic is an “improvement”!!! Condensation won’t be a significant issue with ALUMINUM. If you used iron sheet metal to cut costs then yes I could see that being a serious problem!
Since the “warm side” will be the outside facing down it shouldn’t be a significant. Besides don’t they use Aluminum on Airstreams and they last forever!!!
I’m talking about Aluminum thick enough to be ridge (about like plywood would be). If I go to the trouble and expense it will be done right...
