There was a recall on the tail gate support wires, with which we had no problems. A notice was received and they were just replaced without question or any problems.
The back of the front driver's seat pops, when you first lean against it, like it is made with cardboard inside. Overall, the seat is comfortable, I just question the long term internal quality of the seat.
I am overall very happy with this truck. My neighbor bought a Ford F250 and my brother-in-law bought a Dodge 3/4 ton. This GMC truck is better by far.
The inside of the GMC cabin is put together better than the others as there are not any gaps between the panels and the controls don't look or feel cheap. The only interior complaint is the gap between the center fold down back of the bench seat. Papers and other this items that are put on the seat fall through this area and onto the floor of the back seat.
The ride is much smoother than the other two pick-ups. You feel fewer bumps in the road and it corners well. Why sacrifice comfort for durability. This truck has both.
The 4x4 is a wonderful feature and the pulling capabilities have been strong. We pull a 16' stock trailer with 2-4 head of cattle at a time (about 6,000 lbs of beef). It handles the highway grades and back road hills with out a problem under a load.
The owner of an older Dodge said he averaged a little over 20 miles per gallon with his diesel, which had over 60,000 miles on it. This pickup averaged 19.8 miles per gallon (diesel) on the open road (250 miles of highway) with five passengers and a cargo full of camping gear and musical instruments for a high school band.
