I love my truck

Jon ellis, 08/18/2016
2016 GMC Sierra 3500HD Denali 4dr Crew Cab LB DRW (6.0L 8cyl 6A)
I have a 2015 gmc 3500 dually with the durmax. I also put 24 inch 18 wheel style wheels with larger tires. My truck rides great and i had as much as 21 mpg on the hwy. I average about 15mpg but i do a lot of stop and go and sitting in Atlanta traffic. I have a 26 foot trailer and when i pull it it doesnt even feel any different. I had a ford f350 prior and i had nothing but … issues. I also have new a ls460 but i rather drive my truck.
