The fuel economy of this truck leaves a lot to be desired. My truck is GPS'd so I am only able to drive the speed limit without getting in trouble. The best I have ever got for fuel economy is 14.8 mpg (imperial gallons). The quality of the truck is less than desirable. In cold weather (less than -20c) the back doors will not latch completely without slamming them hard. I actually knocked the molding off the door trying to get it latched. When the doors are closed they squeak and rattle so bad you have to turn the radio up. I have had to install a second battery to get the truck to start after sitting for more than 3 days. The airbag computer already stopped working and needed replacing.
The interior ergonomics is nice. I really like the self dimming mirrors. Seats are what is expected from GMC (very comfortable). Sounds good at the exhaust pipe.
Fuel economy would be nice. Quality need to be built into this truck. How about a rear bumper that actually takes a hit and doesn't fold like a cheap lawn chair.
