2011 Chevrolet Avalanche's case, it's the combination of both pickup and SUV attributes that proves to be so appealing. The Avalanche is based on GM's full-size truck architecture and comes in a four-door crew-cab body style. Unlike a truck, however, the Avalanche's cab and bed aren't separate; instead, the Avalanche features an SUV's one-piece body.
Separating these two sections is an innovative "midgate" that gives the Avalanche its unique flexibility. With it in place you have a quiet, comfortable SUV-like interior; fold it down and you get an extended cargo area that stretches all the way from the lockable tailgate to the back of the front seats. The three-piece hard chevy tonneau cover over the bed can either be left in place to keep cargo secure or removed to carry taller items like dirt bikes or large home appliances. As with all big trucks, the Avalanche's main downside is its plus-sized dimensions, which can make it a handful in heavy traffic and tight spaces. The other notable downside is a price tag that's substantially higher than comparable crew cab pickups.
