Bold and aggressive styling; rugged interior on Work Truck trims; CNG bi-fuel capability; EZ lift/locking tailgate; best in class 18,000-lb conventional tow rating on 3500HD
Fifth-wheel tow rating falls short of RAM 3500HD by nearly 7,000 pounds; Denali trim available only on Crew Cab models; no manual transmission offered; side and curtain airbags not standard on all trims
A bi-fuel compressed natural gas (CNG) 6.0-liter V8 engine is now available on the 2500 HD Extended Cab. Powertrain grade braking on the 6.0-liter powertrain can now operate in normal mode. Previously, engine braking was only available when tow/haul mode was engaged.
With so many trims and configurations, it is impossible to say which model is the overall favorite. Much depends on your needs. If you're not a site manager or oil rig crew, and if you just need a big truck for towing a vacation or horse trailer, the Sierra HD Denali will most likely please you. Those looking for a workhorse should consider the 2500/3500 Work Truck, while those needing both a work station and a family hauler will likely find the 2500 SLE strikes a nice balance between features and price.
The GMC Sierra HD comes in myriad trims, body styles and configurations. 2500 and 3500 models can be had in Regular, Extended or Crew Cab, with 6.5- or 8-foot beds, single or dual rear wheels and 2- or 4-wheel drive.

RAM 2500/3500 HD -- The RAM HD out-muscles and out-tows the Sierra, in some cases by as much as 7,000 pounds. The RAM's Hemi V8 offers more horsepower and torque than the Sierra, but the RAM's ride can be rough and its long-term resale figures are not as strong.
Ford F250/F350 -- Ford's heavy-duty trucks offer more horsepower and torque, more trim and cab options (such as the King Ranch and Platinum trims) and more sophisticated audio and infotainment systems (SYNC).
