Yes, I am for sure getting a dually. Where my confusion comes in is GCWR. Not being able to find good info on that. I have seen info on trucks that are listed with a GCWR of 16,000LBS. the numbers don't seem right.
GCWR isn't posted/stickered on our trucks as too many things like axle ratio's or a different tranny or different hp ratings in the same engine/etc can change a truck makers GCWR usually found on a brochure.
Good luck on finding a one ton anything diesel that doesn't have 150-200k miles on it......or has been a play toy with a big hp plug and play box.
