I had a 10x20 shed delivered by one guy on a roll-back. Once off the truck he used 5-pcs. of 6" dia. sch40 PVC pipe and smeared them down with full strenght dishwaeh soap!! Worked like a charm When one pice comes out take it to the other end and keep it rolling I think it will work for you!! Good LUCK Oldie but newbeebie jimbobboy
