The Chevrolet Avalanche hit the North-American market in 2001 as a 2002 year model and was based on the Cadillac Escalade EXT wheelbase.
This full-size pick-up truck featured a light gray plastic body cladding, used to help customers make the difference between the new Avalanche and the Suburban/Yukon XL. It came with a choice of 2 engines and a brand new fascia (as compared to the classic Chevrolet models). Due to customers complaining about cladding problems following sunlight exposure, the Avalanche was also available without the feature starting mid-2003 (known as the WBH version).
