The Avalanche, which was introduced in 2002, upset the trend of making more SUV-like pickups. The 2009 Avalanche is a unique truck/SUV combo which features a midgate that expands the cargo area into the passenger cab. By removing the midgate and folding down the second-row seat, the cargo floor extends from 5 feet, 3 inches long to more than 8 feet long. The cargo bed also features lockable, side-mounted storage. A locking tailgate and cargo cover increase the secured-storage options even more. The Avalanche is available in LS, LT and LTZ trim levels and in two- and four-wheel drive.
