I owned a 2001 7. 3L PS F-350 Super Cab 4x4 that I had to bring it back to the dealer several times over a 8-10 month period. The truck went back for a leaking pinion seal (3 times), defective vacuum motor (controls the vents), defective driver's window switch, A/C system (would produce a major thump under the floor when you started the truck w/ the A/C on), weak hydroboost steering system (couldn't turn the wheel more than a 1/4 turn with your foot lightly on the brake pedal) and creaking/squeaking doors (adjusted numerous times by the dealer with luck. Dealer finally said I had to "close the rear quarter doors very hard, using one hand at the top and one at the bottom of the door"). While I loved the color (Toreador Red w/ Medium Parchment leather interior) and the diesel, the problems and the all around poor fit and finish were enough to bring back home the Cummins.
