2021 GMC SLT 4WD SIERRA, Great Truck
By Ransom1 on 10/15/2026 4:18:42 PM
This is my 8th truck. This is hands down the very best truck I’ve ever owned. Not only is it the best looking truck on the road I have never had it in the shop except for oil changes and scheduled maintenance. The silver does not show dirt or grime. - 5.0
Great 4 cylinder truck
By Steve on 9/23/2026 2:01:15 AM
I have only pulled a trailer one time and still got 18 mpg down doing 80 down the interstate. Otherwise this vehicle is used for commuting or recreating. I typically get 22-24 mpg driving MT highways to the mountains. The turbo has some spunk for getting up to speed and the five years I've had my truck no complaints.
