Overall no "major" quality or reliability problems, but enough to be annoying. Require several premature repairs after basic warranty; passenger door lock intermittent, rear sliding glass windows leaked from day one, cup holder spring broke, check engine light on and $300 sensor repair at 37 months (just out of warranty), cheap tires, brakes needed at replaced at 25K mikes, Cruise control sometimes acts erratic and disconnects on its own. Engine is powerful. Body finish is still excellent. Only big negative was that Ford service could never duplicate rear window leak (floor always wet after every rain). I finally repaired the leak myself.
Leather seating comfort, interior room, visibility great, easy to drive, smooth ride, hauls a lot of stuff. Best attribute is the brawn, toughness of the suspension, and ability to pull a bunch.
Factory tires were substandard and need upgraded. Workmanship quality could be improved; preventing rear glass from leaking and getting interior wet. All the rattles should be eliminated for a $29K truck.
