2008 Chevrolet Avalanche SL1

General Motors introduced a novel concept for 2002 with the original Chevrolet Avalanche sport utility vehicle/pickup crossover. A trick midgate could fold into the four-door cab, extending the cargo bed to the back of the front seats. It gave owners the best of both worlds: seating for up to six occupants or a long cargo bed when one was required — a combination that would require ungainly exterior dimensions if it weren't for the conversion feature.
