2015 SLT Z71

I have the 5.3 4x4 with 3:42:1 rear axle, the truck seems rather sluggish to me. What I hate is how it is always trying to shift up to a higher gear which makes it slow. Not a day goes by that I wish I had purchased the 6.2 but in order to get that engine you have to upgrade from SLE to SLT, lost more money. I think it's stupid that GMC won't let you select whatever engine you want it the truck.

Great truck with some minor flaws

All in all its a great truck. The flaws that I seen so far are these, but not enough to sway you from not buying. Love the heated seats and auto start. 1.) Head lights Suck. 2.) Head rest feels like a brick. Probably so you don't fall asleep. lol. 3.) Needs more storage space like on top of the dash or center console style changed. The 3 sections behind the cup holders on the split seat styles are completely useless and waste of space. The dividers need to be either removable or gotten rid of. Would be a nice place for pens. Also the bottom center could pull out with a nice configuration there. Instead you have to lift the bench to get it opened. 4.) Ride is a little stiff, but that could be because its still new.

Been looking at trucks and settle for the 4x2 SLT

looking for something for my activities cycling/Kataking and taking my dog with me. This was the perfect fit. Luxury inside and all my toys in the bed. Think it drives better than my car I had. Very very quiet rude. No more dog hair inside. I place my kennel in the bed and now my dog ( Cooper) goes everywhere with me! I have the Texas Edition SLT and love it!
