Can anyone tell me exactly what a cab and chasis 4500 weighs? Reg cab, 2wd. Gross is 17,500 and i don't see that cab and chasis coming in at 8,000 lbs leaving me 9,500 lbs to work with.......from which a body must be subtracted, fuel, tools etc. Maybe I'm wrong, I don't know. Local dealership couldn't tell me anything but they sure could order me one........morons. Thing is the one I bought is sitting at the shop and I have to let him know to do aluminum or steel bed and it all depends on the weight.
