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.

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.

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.
