It hasn't changed much for the new model year, but the 2011 Chevrolet Avalanche really didn't need to--it's offered some seriously upscale options since it was introduced a few years ago.
The basic Avalanche, the LS, is intended more for the work crowd though it's quite nicely outfitted. It has standard power windows, locks and mirrors; keyless entry; a power driver seat; an AM/FM/XM/CD player with MP3 capability; a USB port; and steering-wheel audio controls. LT and LTZ features add on some more luxury features from a list including a navigation system; Bluetooth; Bose audio; leather seats; power-adjustable pedals; remote start; and ventilation for the front seats.
A specific Z71 package loads up the Avalanche for off-roading, with recovery hooks, fog lamps, and distinctive trim.
All Avalanches get the Midgate that expands the pickup bed into the cabin, and all get a three-piece locking cargo cover, nonslip bed mats, and a locking compartment in each rear fender.
