I have to build a leafbox to go on my dump truck. Its an easterner dump bed with about 2 foot sides on it currently. I took the time on the sides when I built them originally, so they would last. All pressure treated 2x6, Faced with alum. diamond plate, stainless hardware, large stainless eye hooks on the insides for tie downs, etc. I want to build something thats going to last. I think a top hinge is the best design that I have seen. How does the box get loaded onto the trucks typically? Or does it get assembled every year? I was going to use PT plywood and supports. I am thinking another 4 feet taller? What would be a good paint or covering over the wood? Would you build a different setup or just attach the box to the sides I have now? Any tips, build pictures, do's and donts are all welcome. I do not want to screw plywood together like last year! Thanks!
