This has been a great truck. I drive it off road about 4 weeks a year and in the snow during winter in Colorado. It handles either great as well as dry pavement. It could get better mileage but hey, it's a full sized SUV what do you expect?
I like the short wheel base and its super easy to maintain. The engine compartment has plenty of room to get around in. and lots of cargo space.
More ground clearance would be nice but lift kits can handle that. A new 2dr version from GM would be nice too.
