Okay. I have a 2003 F-250 Crew Cab with a 6'10" box and the truck has a 3" lift. I want to be able to put two Pro RMK's on it in the winter, and a 1000 RZR on it in the summer. Sled decks scare the crap out of me. So I was thinking maybe a flatbed. (There will be times I will want to put the box back on too!) I can build a flat bed made out of iron if I can find a good set of drawings, and I would have it either professionally painted or maybe have it coated by the same outfits that do box liners. What about aluminum? An aluminum deck I would have to buy. I can't weld aluminum. Ideas, thoughts? Anyone know where I can get a good set of drawings? (Blue prints)
