Best HD Truck Ever !
By BZ | on Thursday, April 09, 2020
After owning a 1500 Sierra and stepping up to a 2500 HD Diesel there is a night and day difference when towing, highway MPG is surprisingly good for a 8000lb vehicle, average between 20-24 depending on conditions. Towing mpg is much better than gas V8. No strain at all on vehicle when towing. Truck has been 100% reliable so far @ 19K with zero issues. Allison transmission is the best I ever used, nothing else compares to this transmission !… - 5.0
This truck is awesome
By Army Vet | on Sunday, May 26, 2019
I love my GMC. It is reliable, well built, comfortable (my wife loves to road trip in our GMC) and gets excellent mileage (20-24 MPG on the hi-way). The truck drives well and is very solid feeling. The Duramax/Allison duo is unmatched in my opinion.… - 4.0

Kelley blue book is great. I recommend it to everyone. It gave me that answer I wanted. And now I feel comfortable.…
