Mine is a 5.9L Auto/4x4, but that wasn't an option. Overall this truck has done its duty without any major issues. My dad bought it brand new and i bought it off him 3 years ago. Took good care of it but worked it hard too. They are good for what they are if taken care of. Even with the 5.9L it is underpowered vs newer trucks but we have towed all the way up to max capacity without issue. Gas mileage is atrocious but what do you expect? With 141k miles the only "major" issue is the evaporator went out a few years ago so the air doesnt work, and its an expensive repair. People don't seem to treat them right, but if you do find one that has been taken care of, you can't beat them for the price
4x4, torque, large center console
More horsepower, down low torque is great but it needs more horsepower for freeway speeds, especially when towing passing/lane changing power isn't there. More refined interior, better gas mileage. Also the gearing, 3.55's are not a good ratio for this truck. 3.92's or so would be about perfect.
All of this was addressed in the next generation.
