The Chevrolet Avalanche, one of the most desirable crew-cab pickups for carrying passengers and cargo, has been commended for its useful passenger accommodations, expandable cargo room, big-truck muscle, and friendly road manners. The 2008 Chevrolet Avalanche truck is available mainly in two trim levels LS and LT; there is also a premium line-topping LTZ package. For 2008, changes are minimal, but include standard side-curtain air bags and satellite radio for all Avalanche trims.
