The biggest selling point of the 2011 GMC Sierra 3500HD Denali can be found in its power and strength. Most of the power of the truck is due to the use of an independent front suspension. This pick-up is easy to use and maneuver on straight roads and all turns and corners, which may seem like a challenge for other heavy duty trucks and pick-ups.
In general, one can count on the impressive hauling and towing capabilities of the pick-up. In fact, it was rated as the best in its class- even pulling ahead of Ford and Ram. 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;
Overall, this is an excellent all-around HD truck.
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.
Passengers are provided with ample space in the front of the cab, but the bigger passengers may be troubled and inconvenienced by the limited 39 inches of leg room at the back of the crew cab;
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.
