Good Dependable Truck. My truck came set up with trailer brakes
My truck is a 4 door. It has a great stereo, AM, FM and CD player. Cruise control, adjustable mirror and seats. Good on gas mileage and very comfortable to drive and ride in. You can fit 6 people. Has a tow package. Has a bed cover and came with window trims.

The sierra 2500 had is a very reliable truck.
I really like our truck. It is perfect for pulling our camper. I also like that there is plenty of legroom for my husband who is six foot four inches. We have owned this truck for two years and we have not had any mechanical problems a all.

Great Truck that gets the job done!
It's been a really reliable vehicle. It pulls my camp trailer really well and has lots of room for my family. The long bed makes it easy to haul lots of stuff. Having the 3/4 ton version makes it so I can haul just about everything. The only thing I don't like is the lack of power windows.

Great truck, fantastic towing capacity for a gas engine.
I love most things about the truck: it is towing capacity is fantastic for a gas engine. However, I have had to completely replace the factory assembly transmission fluid lines. So I think those tend to go bad on GMC trucks. That is a pretty big replacement. It cost about $800. Otherwise it is been a great truck.

A regretful purchase, a lemon all the way around.
The fit and finish on this truck is terrible. The buttons on the dashboard are all worn down, the dashboard cracked twice, and a it leaks when it rains. You have to shift in manual when using tow mode because it doesn't shift at the proper points, even though I had the transmission reprogrammed at the dealership. It also has grounding issues. I am very disappointed in this truck, after having a Silverado for years I thought I was upgrading but I was not.

My truck hauls great handles well and has enough power to hall.
I love my vehicle I think it is great for use of a need for a pick up truck. I do not think I could drive anything else other than a truck and I love the GMC c are.
