I analyze more than I actually do stuff, but my current thinking for my van is to put up 1.5 to 2 inches of styrofoam (panels), and then use straight pins to pin quilts, blankets, or bed comforters to the walls and ceiling. They'll come down real easy to wash, easy to go up, easy to come down, easy to find cheap at church sales, and should be good insulation. I've never seen it done before but I think it will work good.
