Dump bed on non-dually F350
I am contemplating purchase of a hydraulic dump bed for my 1996 F350 7.3 crew cab. (4x4, automatic, 8 foot bed currently). I would appreciate some input regarding the addition of a dump bed on a single rear wheel set up. My plan was to remove my current bed and store/preserve it as it is in pretty nice condition and it would be good to go with the truck if I ever sell it. That being said, do I need find an outfit to do a dually conversion, or will my single rear wheels and tires hold up. For that matter, do they make a single tire that will withstand as much weight as a dual setup.
The reason I am considering the addition of a full size dump bed is that this appears to be a more feasible route than buying another truck in the higher weight class range. I do not want to frinlkle around with stopping at weigh stations and getting a CDL and the upkeep of a physical card. My F350 with the Warm Classic winch is a good, practical rig for me, I just need more hauling capability.
