I thought this link might help you. The Fast Lane Truck did a review of the truck comparing it to the 2014 F250 and Silverado 2500. My friend at work recently bought one 4x4 with a 4:10 rear end axle ratio, 17,000 lb tow rating. It also has cylinder deactivation. What I think is really neat is the new rear suspension system rear coil springs and factory installed rear air bag. It's a very nice truck!
