Not sure on what truck your all talking about but look, my one ton dully ford 4x4 iron 460-4 speed 4x4 D60 front and back, Full 8 ft one ton flat bed with tool boxes sits full of gas at 4600 lbs.
I think you should add about 2500 pounds to the 4600
it's ok to butt heads, just don't do it with a butthead
