So the rigid insulation was a total win! The night before last we stayed in a field for an Enduro event I raced yesterday. Temps were mid 40s but dropped to 32 by morning. There was no condensation on the ceiling other than two three inch strips where I did not install bc I ran out of material. It was soaked in these spots and dripping. I'll get some more and glue it up there but other wise I'm happy!
