The 2013 Chevrolet Avalanche truck is part pickup, part SUV and entirely practical. Its big, roomy cabin is virtually identical to the Chevy Tahoe and Suburban, from the second-row seat forward. Out back is a pint-size 63-inch cargo bed. A unique folding midgate bulkhead between that bed and the flip-down rear seat extends the cargo area into the cabin, providing many more options for hauling bigger loads. Built on the same platform as the Suburban, the 2013 Avalanche full-size truck is endowed with the same strong chassis, ground clearance and available 4-wheel drive (4WD) as its SUV cousin. Chevy has announced that 2013 is the Avalanche's last year.
