It is not that insulation is too thin most of the time, but that manufacturers leave lot of voids in it.
My upscale camper has attic with good insulation I can see around vents, but when I pulled the light - I could stick my finger into wires hole and felt nothing behind. Than front cap had some loose fiberglass that with leak turn into pile of garbage.
Than I would hope that for that kind of money they would spend couple more bucks for polyurethane foam, not Styrofoam.
Polyurethane has better R value and is much stronger.
I had my 1972 Prevost conversion sprayed with 2" of polyurethane and regardless steel construction, that transfer the heat, I could keep 40' coach cozy with single electric heater in those off-season nights.
Same heater was not enough for 20' ClassC with thinner walls and Styrofoam.
