The Chevrolet Avalanche is a full-size SUV with an open bed in back as opposed to the normally covered, wagonlike cargo compartment. The midgate feature allows one to quickly change this rig from a five-to-six-passenger crew cab pickup with a 5-foot 3-inch cargo box to a two-to-three-passenger pickup with an approximate 8-foot cargo box. Bonus features include removable cargo covers and storage compartments placed along the outside of the cargo box., , There are three trim levels: base Avalanche LS, midgrade Avalanche LT and plush Avalanche LTZ. All models are equipped with a 5.3-liter V8 (320 horsepower and 335 pound-feet of torque) that's matched to a six-speed automatic transmission. LS and LT 4WD models get a single-speed transfer case, while a two-speed transfer case with low-range gearing is standard on the LTZ and available as an option on other trim levels., , In reviews, we found the Avalanche to be comfortable and smooth-riding for such a capable workhorse. Performance is sprightly considering the Avalanche's heft. The big truck is relatively easy to drive on open roads, thanks to precise steering and predictable handling. Maneuvering in tight spots is tough, however, due to the Avalanche's massive size and considerable blind spots astern.
