I have a c10 short bed that I am in the process of building and as of right now the only body I have is the cab and doors. I was thinking of ways to lighten the box. I've seen guys build a frame out of sqaure tube then mount box walls to it this might be the route in which I want to go seen's how I'm not going to haul anything (4 in drop mono's with caltracs) or tow anything (540hp lq9 with a pretty lumpy cam). How are these done? or is there another way to shave weight out of the box?
