Overall a very reliable truck. Never had any problems w/ the drivetrain or any major mechanical issues. That said, the brakes are awful and the ball joints are junk - getting them replaced by Dodge, even with a recall, was a real hassle. Fuel economy averaged a disappointing 15mpg, and the 3.9 V6 just does not have enough power to get the heavier quad-cab moving or passing with enough authority. At highway speeds, the ride is smooth for a truck, but very noisy. Had to upgrade sound system just to hear the music. After 50k, it still runs great, but I should've opted for the V8 instead. This has been one of the most reliable vehicles I have owned, but more power is a must for a truck.
Quad-cab rear door opening angle, Factory Infinity stereo system above average. Roomy interior & full size back seats (not just a plain bench). Intuitive instrument cluster & dash layout - good positioning of switches.
More fuel economy or more power. The V6 has neither. Better sound insulation from road noise.
