Extremely nice truck

This truck is perfect for what I need for my business and family. It has plenty of room for hauling my dogs, pulling my horse trailer and carrying my family.

Best truck so far

by Chuck Lysse from Shelby Twp, MI | January 16, 2020

Excellent all the way around, meets all my expectations and more. Love the front end, it has that "truck" look, which made my decision easy.

Never owned a truck before..

I bought this new 2018 GMC Sierra SLT new in Sante Fe, NM. I never owned a truck before. I traded in my Tahoe 2011. I am truly impressed. It has all I could ever need for comfort, looks, amenities and performance. I bought a Red with gray leather interior and a sunroof with 5.3l V8. I did change out the Goodyear tires for Bridgestone Alenza Plus HD, which make a huge difference in ride. I get a lot of compliments on the look. I am very happy with my GMC. So Far
