never go by the door sticker lol. Not on a dodge ram. They're NEVER right. an 04 Dually Cummins quad cab would be a tad under 9000 lbs. We have an 03 I'm putting the clutch in on later this week, on the certified crop scales(accurate to within 5 lbs), it weighs in 8860. It's the length of the arms I'd be concerned with.
