I purchased the vehicle thinking it would be better than my previous truck, but I was mistaken. I did like the color and the sizable back seat as it is a crew cab. I was also very happy about not having the large touchscreen on the dash! I looked long and hard to find a fairly new truck that didn't have one. The week after I bought it, the bed started squeaking and has continued to ever since, without anyone being able to fix it. The stereo that comes in the vehicle isn't very good, but I do like having the controls on the steering wheel. The electronic display of features, including tire pressure and oil life, were nice to have, but the fuel mileage wasn't what I was hoping for. Overall, it's a decent vehicle but not worth all the hype that I had heard.
Story
It has been great to tow our little box trailer/camper that we made with. My little yorkie likes to make her bed in the center console, and as we get ready to go camping, she hops up like a champ and snuggles in for the ride to OH! Every time we start to get the camping gear around, she waits for her seat to be ready for her!!
Pros
The truck sits well and drives well. The running boards are a definite plus for us short people trying to hop up in. I do like that you can fit six people in here as the center console lifts up for an extra seat in the front! The room in the back seat is amazing, much more than most crew cabs trucks. The look of the vehicle is sharp, and I do like it. Digital displays of the tire pressure, oil life, mileage, etc., is great to have with the click of a button.
Cons
The fuel mileage is very poor, averaging no more than 15 mpg at a given time. I have had sensors all over the vehicle go bad and a terrible squeak that not one mechanic can figure out. We have learned to live with the squeak, but the check engine light and sensors are definitely a big downfall for this truck!

This is a solid, all-around performer. Rugged and heavy duty. It has the balls to get the job done when called upon and just enough finesse to please the little lady and get the kids home safe.
Story
Too many to count . The most recent was two weeks ago. We were four-wheeling down along the creek. My buddy dumped his warthog in a ravine about 15 feet over a ledge. Luckily the ground above was solid enough that I was able to pull my GMC up to the edge and drop the winch down to pull my buddy and his warthog out to safety. Game on!!
Pros
The 4x4 is unmatched. Power and traction all the way.
Cons
I wish it had more cup holders.
