Other excellent things to note include the responsive steering, excellent and comfortable seats, and quiet, smooth ride quality;
The engine used by the pick-up is one of the best of the class. Buyers are given a variety of engine choices to choose from including the most popular and most powerful DURAMAX diesel engine;

There's no denying the fact that the 2011 GMC Sierra 3500HD Denali Truck is good looking but there are some minor issues that buyers can't deny. One thing that is distracting is the use of small buttons on the center stack which can be annoying at times.
The cabin storage needs improvement and drivers will miss the telescoping steering wheel on this pick-up.

There are some minor ergonomic issues that can be found on the vehicle and some drivers may also note the troubled downshifts, when driving the 4-speed automatic transmission.
