I mainly plan on using the van mainly as a weekender but plan on spending time in the snow and would love to stay as warm as posdible without running heater all the time. Any ideas would be greatly appreciated.
I used EZ cool (Reflectix is also used, but more expensive) rolls on the exterior walls and floor. On the floor, I used foil faced rigid Styrofoam and on the walls I used 1 1/4" ROXUL for the walls. They kept the heat in and the cold out!
