Ok - working with a fabricator and swampman's design.
He's going to quote 12ga and 16ga steel for the lid.
Says because of the design that he can't make it from one piece. One of swampman's posts on his build does say the top was bent from one piece.
Assuming that can't be done and a seam is necessary - run it lenghwise or width of the trailer...or look for a fab shop that can make the top piece (not ends of course) from a single sheet?
