Well, use what you need until you're finished and scrap the rest. That's my plan. I saved the ceiling steel to box in some insulation, then insulate over that to add rigidity to the body. The thermal break will help as you insulate over the steel. As far as the chairs go, I scrapped mine in California to make my trip legal to Texas (leave it to the progressives to make a mountain out of a mole-hill). So that's my observation............
