I really enjoy my Tahoe. I purchased it because I need a 4wd vehicle to get me to and from the fire station during snowstorms. I have been impressed so far. Besides the gas mileage, I'm very happy with it so far. It has over 120,000 miles on it and I feel comfortable driving it across country. Although I am a light foot when I drive on the highway, I still only average 17. That said, I love it and I bought it knowing what kind of milage a 5.7 v8 gets.
Comfy seats. I'm 6'6" and 230 lbs and sit very well in the truck. Plenty of room for my other 6'6" friends to sit in back.
