Andy, i think you are gonna have to spring for a 102" gooseneck or something of the sort. It is definatly gonna have to be a deck over trailer. those axles are gonna be close to normal full widths if you use hummer rims. Davids 42's stick out about 3-4" on each side of the tub in the rear. I think brian richey's 33" TSL's stick out farther then that on a stock rear axle....
