Default 2018 gmc
I tow a 8000 lb. Cobalt boat with a 2015 GMC Denali XL and get 11.5 mpg and it has a 6 speed transmission. I too purchased nothing but a 2500 Suburban with a 454 or 496 but when they switched to a 6.0 it sounded like a circus organ shifting All the time. You will be VERY happy with a 2018 GMC Denali XL. When not towing it gets 23 mpg! And I own a gas station!
