FYI, I have a 2500 Quad Cab 2wd short bed 5.9L Cummins Diesel 4 speed auto trans. I love this thing, it gets better mpg towing my 6500lb trailer then my '03 Hemi did empty. Wish the shocks were a bit firmer. Interior is simple and clean. Been real good to me so far, 2 months and 5400 miles. 13mpg towing, 20mpg empty, and with all that torque, it makes it fun to drive on the freeway, passing is a breeze, no down shifting needed.
The POWER, endless power with the Cummins Diesel, 14,000lb towing capacity
