Avalanche is unique. It stands up to hard use on the road and in the field. And it's easy to change up. Part powerful truck, part upscale SUV, the 2012 Chevy Avalanche is total versatility. It features the GM segment-exclusive Midgate® located behind the rear seats that can be easily lowered, transforming Avalanche from a roomy SUV into a serious pickup truck with an 8-foot 2-inch cargo box.
