I like how mine came out. I used some heavy sheet steel, about 1/16th, and it took almost the entire 4x8 sheet to build the walls and fenderwells and fender extensions, boat sides, etc. I cut off the tail, built the bed out of light 1.5x1.5 steel, tacked the tail on the end, and made the bed out of an old Toyota bed
edit: that didn't make sense
The bottom of the bed is cut from the bottom of a toyota, I mean. The side rails of the light 1.5 square tube, offset to make that "stepped" bit at the top that Zuks have, as I didn't have access to a bunch of Samurai sheetmetal.
here's the "before"
