This truck is a dream. Comfort and ride of a cadillac with the power, handling and driveability that will make you want to go on a road trip. My tall children and elderly parents are comfortable in the back seat. I literally have nothing bad to say about this truck. I love it.

This thing hauls my boat or camper with plenty of torque to spare. 4wd is smooth and really climbs. Beautiful interior and body style

@ 55000 miles I have replaced the starter, 3 condensers , oil cooler radiator , vacuum pump,@ 100,00 rebuilt transmission , and the GPS tells me I am in the North Atlantic, now being a retired Merchant Marine Captain I'm pretty sure I'm not in the North Atlantic. I have owned GM products since 1966 and this is my last, and oh yes when I went to replace rear brake pads the emerency shoes where not installed correctly

2015 GMC Sierra review

If your looking for a good daily driver pickup this one is fairly comfortable to ride in and handles good in different conditions. The fuel economy isn’t too bad. The manufacturer says 17-22 but I think they are on the high side. I saw around 16 mpg with mine, maybe 18 or 19 highway. I wouldn’t recommend it if your looking to tow anything heavy or plow . The 6 speed tranny isn’t made for it in my opinion. Maybe the 8 speed and 6.2 liter engine would be better suited for that.
