Hi I'm new here. I've seen some discussions of materials for campers and I didn't want to resurrect threads from 2012.
For those of you who have built/upgraded expedition campers. What target R values are you going for for: Roof, Walls, Floor?
I have found some good recommendations for houses and here are the numbers:
I will post for regions 3 (California) and Region 7 which is cold places like Alaska
-------------- region 3 | region 7
Attic (roof) R30 to R60 | R49 to R60
Wall (cavity) R13 to R15 | R13 to R21
Floor ---------- R25 | R25 to R30
