I love this truck. The only problem I had was it was hard to find. I think the Chevy/GMC 1500HD 6.0 4x4 QuadSteer was the greatest pick-up ever built. My job requires travel, & it's a dream on long trips. Plus, it's fun to run Civics & Mustangs around town! Testimonial: It pulled a 1 ton Dodge diesel towing a 65 hp tractor & implements on a gooseneck trailer, about 500 yards out of a muddy pasture in the pouring rain. It was buried to the axles. Even when I initially freed him he still couldn't move an inch. The owner said "that 6.0 can tot the mail but" His jaw dropped when I pulled him all the way to the road. Towed a 4Runner on 20 ft. lowboy through downtown Houston with no problem.

Special Ordered 2WD with all options except the OnStar and XM Radio. Commuting in city to work average 17 mph, 15 on trips, 11.8 towing 34' Avion has 4.10 axle. Will get 22 mpg @ 50 mph but who can drive 50! Several build issues & recalls but great truck except am now getting noise from the rear emergency brake drum caused by not using the parking brake and told its common problem with GM 4 Wheel Disk Brakes rusting from non use. First trip from Indiana to Ruidoso NM we averaged 12.1 going and 11.8 returning with 34' Avion in tow with temp at 112° in NM. Great fiberglass bed, electronic suspension, dual memory driver setting, free extension for the rear safty belts. Love computer display

The seats are very comfortable, great for long trips. Could use more power and better mileage but it does have a 6 inch and 35 inch tires. Still has the power to spin the tires with ease. The truck also tows very well. Interior looks great with plenty of room being a crew cab.
The Sierra gets a new look this year that includes a new front fascia and revised side moldings. On the inside, the Sierra offers new entertainment options, such as a Bose audio system with rear seat controls, XM Satellite Radio and a rear-passenger DVD entertainment system. The instrument panel and center console have been redesigned, and GMC has added new seats, a more comprehensive driver information center and a dual-zone climate control system. For increased safety, Sierras now feature a standard front-passenger-sensing system that deactivates the airbag for children. On the hardware side, the all-new Quadrasteer four-wheel steering system, which increases low-speed maneuverability and towing stability, is now optional. The standard 6.0-liter V8 gets electronic throttle control, as well as the ability to run exclusively on Compressed Natural Gas (CNG) or a mix of CNG and gasoline.
