I have a 2006 Tahoe. It had the "0" motor in it which was the better of the two that Chevy installs. At 197,00 miles the cam shaft went bad. I loved the vehicle so I had a new motor put in. Two things I don't like about it. Doors have no drip edge so water will drip onto the control panel for windows and doors. This caused a short and I had to replace the panel. Spare tire under the truck is a pain in the butt to get off. Other than that I still have it at 215,000 miles and hope to get another 100,000 out of her. Good luck.
