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.
Even though, for several decades, GMC has represented little more than a rebadged Chevrolet, for 2007 GMC made a concerted effort to distinguish itself from its divisional sibling, while GM's engineers made a concerted effort to increase the differentiation between the Heavy Duty pickups and their lighter-duty counterparts.

"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 have the SLE crewcab with 4.8 liter. never have I driven a truck with such a small motor that makes so much horsepower. I use this truck for commuting 90 miles a day and gets 23mpg down hill and 18 mpg up hill if you drive with cruise on and use neutral down hills. I use to have an S-10 4 cyl that got 21mpg all the time. this ruck does average 15-16 mpg depending how you drive it. Cruise control definitely helps. I was worried at first that I should of bought the 5.3 6speed model. After seeing reviews and feeling all this power, Im glad I bought it. I think the engineers at GM have this motor maxed out with horse power so to add a cold air intake or some loud exhaust system would be a waist of time and money and most likely make it slower and lower MPG. I run my tire pressure at 35 psi and it rides like a Cadillac. when i put 44 psi it feels like and old GMC ready to shake apart and you can feel every bump in the road. I love this truck. Not the fastest thing, but an overall good truck"

"The truck has slack in the drive train. It is more noticeable in stop and go traffic, and when you turn to the right you can hear a clunk noise as the slack comes out of the drive line. I took the truck back to the dearlership and was told by the technician that I was not the only one who had this same problem. According to GM and the dealership the solution was for me to change my driving habits."
