Thanks to an optional rearview camera mounted next to the tailgate handle, seeing what’s behind the 2007 Chevrolet Avalanche can be made quite easy. That’s good for pedestrians, pets, and anything else you don’t want crushed by nearly three tons. Visibility also benefits from the large side mirrors and generous use of side glass. Serving to limit the outward view, however, are the triangular rear pillars and the high sides of the bed, the latter exacerbated by the addition of a tonneau cover. The ill effects of those rear pillars, by the way, are only slightly negated by their center cutouts.
