Just purchased a 24' box truck and going to convert into a "poor man's rv".
Plan on just building a 2 x 4 frame out of wood, then put 2" foam insulation that I have. I built a home using insulated concrete forms and have lots of scraps left over. Plan on using 18" heavy duty foil against the wall, then a layer of 6 mil plastic, then build the frame and add the insulation. It is a fiberglass body.
Trying to prevent mold or other problems. Think this should be enough?
