The 2007 Avalanche redesign has a nicer interior. With an available full-time four-wheel drive system, the Avalanche did very well in our testing. It's also quiet, rides comfortably and the optional rearview camera system greatly improves outward visibility to compensate for a very large rear blind zone. The versatile cargo area has a watertight three-piece cover and two locking bins on the sides. The rear window can be removed and stored in a compartment on the midgate for taller items or left in place along with the bed cover for weather protection. This modular system provides several options, but in practice is fussy to use. The rear window is somewhat heavy, and both rear seats have to be folded in four steps to move either the midgate or the rear window. Model year 2013 was its last.
