Since its introduction in 2002, the Chevrolet Avalanche has won over tens of thousands of consumers with its ability to adapt. As an SUV with the Midgate closed and the rear seat up, the Avalanche can comfortably transport six people, and as a truck with the Midgate folded, the Avalanche's truck bed grows in length from 5'3" to 8'2". The Avalanche is, without a doubt, the most flexible SUV on the market.
