Narrow year range (drag arrows to filter):
For 2013, extended-cab 2500 HD models equipped with the standard 6.0-liter V8 can be had with a new bi-fuel system that accommodates both gasoline and compressed natural gas (CNG). Two new exterior colors (Sonoma Red Metallic and Heritage Blue Metallic) round out the changes.
The 2012 GMC Sierra HD sees a few improvements for this model year. A new hard-drive navigation radio is offered, while Work Truck models gain cruise control and lockable spare tire. Denali trims gain as standard equipment heated and cooling front seats, a heated steering wheel, a rearview camera and, on 3500 dually models, 17-inch polished wheels.
The 2011 GMC Sierra HD's Duramax turbo diesel's power, torque, maximum conventional and fifth-wheel tow and payload ratings are best in class. Its fifth-wheel tow capability is 21,700 pounds, it can tow up to a 17,000-pound conventional load with its factory-installed hitch, and the Duramax is fully B20 biodiesel compatible.
Technical upgrades include the addition of Bluetooth hands-free communication technology to OnStar 8.0, as well as Destination Downloads for vehicles equipped with DVD navigation. Extended and Crew Cab trims offers a rear backup camera, while a stability enhancement system is made standard on the 2500 HD with single rear wheels.
When the task at hand calls for more muscle than a conventional full-size truck can handle, it's time to summon a heavy-duty pickup. In both 3/4-ton and 1-ton configuration, the 2013 GMC Sierra HD delivers the type of power and utility needed for the most demanding jobs and does it while providing commendable levels of comfort. To that end, the 2013 Sierra HD lineup offers an exclusive pair of high-content Denali variants to further broaden appeal. Motivation comes in the form of a gasoline-fueled V8 or a torque-rich turbodiesel. Since rival HD pickups like the Ford F-250/F-350 and Ram 2500/3500 each offer of the most hauling power this side of a Class 8 semi-truck, choosing the right brand ultimately comes down to personal preference.

"I got a 2008 work truck with rubber floormats and manual windows and locks. The truck drives great, is very quiet, and gets 20mpg on the highway all day long. I've had no problems with anything in the first 3 years of ownership. My only complaint is that parts of the interior feel cheap, but I did get the base W/T. No rattles or squeeks though. The only options I have are cruise, XM Radio, A/C, and the Eaton Diff. I got the SL exterior appearance package, and I get compliments on my truck all the time. It looks like a $35k truck. You can't beat a brand new truck for $20k that has a 100,000 mi. warranty on the drivetrain."

"I love my sierra. I've had it for about 2 years now and have not had even one problem with it. Very dependable truck. The powertrain is good in both performance and fuel economy. I use it to tow a small trailer on occasion(roughly 5000-6000 lbs) without any trouble. Styling is great... I get compliments on it all the time. The quality of the components and the ride are both top notch. Bottom line, its a great vehicle."

"I own a 2011 Z71 extended cab and so far this truck has been a pleasure to drive. Ive taken the truck up north Michigan camping numerous times and have got anywhere from 19-21 MPG on the highway (5.3 engine). Plan on putting a back-flip cover on soon to ad to security for the bed and im sure my MPG's will also improve. So far no problems what so ever!! ohh and its a smooth ride on the highway !! Could use auxiliary power outlet for rear seating area."
