After having owned Chevy/GMC trucks most of my life, most of them used, I looked forward to a new, fully equipped version. I was disappointed in the quality of this vehicle. The roof is so thin, it "oilcans" constantly if the wind blows. Multiple trips to the dealer were required to quiet most of window the leaks. Repairs have been required to the drive train, the electrical system, the brakes and the steering system. All after the minimal warranty expired. I'm trading this one in. Too much attention to the excellent bells and whistles and not enough on reliability and "truckness".
Heated power leather seats with memory, XM Satelite radio, the electronics in the trip computer. These are wonderful features. The overall comfort and technical sophistication of the truck is great.
Build a better truck, mechanically, and stand behind it for at least 60,000 miles. Put thicker steel on the vehicle so that body panels don't easily deflect, specifcally the hood and the roof. The reliability of the electronically controlled transfer case/4WD is the weakest link.
