I've had two Avalanches before buying a Ford Super Duty for the diesel engine...what a mistake! Don't know if it was the new '08 diesel 6.4L or what, but fuel economy was miserable, 12mpg in town, 16mpg on interstate with no towing. I also missed the versatility of the Avalanche: side cargo bins, heavy duty covers, waterproof rear bed, and the expandable bed size. Not only that, but the EXT adds significant comfort and features: NAV, DVD entertainment, heated/cooled seats, luxurious and beautiful interior, and great looks. Take it easy on the gas pedal and you'll be getting 15-16mpg in town, 20mpg on the interstate. Hauls tools, gear, toys, and projects with ease. The ultimate upgrade!
Expandable and covered bed, side cargo bins, DVD entertainment, NAV system, and great Raven Black looks ;-)
Telescoping steering wheel, adjustable engine mapping for fuel economy, and selectable 4WD.
