I had a 2015 tuned ecoboost crew cab and put 53k miles on it so it was time to truck shop again. I went and test drove a 2017 GMC Sierra z71 crew cab, 5.3, 3.42's and when I pulled out of the dealership broke out laughing at how underpowered it felt compared to my ecoboost. I came home and looked online at some more dealerships and pulled the window sticker up on this truck and something jumped out at me, 3.92 gears. I went and test drove it and as soon as I pulled out of the parking lot I knew I was taking it home. I bought it on Wednesday and I already have 750 miles on it. I am amazed at how much better it drives than my F150 which I really thought drove great. So far there are only two things I don't like about it. I really miss my keypad on my door so I didnt have to carry my keys and I always drive with my left elbow leaning on the door and the way this door panel is shaped it instantly makes my fingers tingle because it's pressing on my funny bone so I will have to do something about that.
