I wish It was a dump truck, but it is not, I said I wish. The price was right for a pick up...Just bought a used p/u truck --1992 GMC.-- my second vehicle, my other one is an extended van. Now, it has some slots where I can put siding so that I can enclose it for leaves, etc . I am trying to avoid using 2x2 from Home depot as framing..... I have noticed that there are special metal frame that other trucks use for siding. Is this commecially available somewhere?
