Purchased the 2500 SLT 4WD QUAD with 5.7L a month ago, and couldn't be happier. You buy these things for utility, drivability, and all around looks. Fuel economy is the only negative I can see with this truck. I have been driving as fuel efficient as I possibly can, and have averaged a best of 14.2 MPG (expressway/city driving). This should get slightly better when the motor is fully broken in. The build quality is excellent as are the interior features. It brakes wonderfully, and maneuvers like you are driving a much smaller truck. I previously had a 2002 Dodge Ram 2WD, 3.7L, 5 spd. This truck was extremely reliable but severely underpowered. Overall, I have been happy with Dodge.
Power, ride, looks, build quality, interior design/functionality and braking/maneuverability.
Work on getting the fuel economy up another 2-3MPG.
