2018 GMC Yukon XL OR 2018 Ford Expedition

[Big Block Bill]

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!

Transmissions continuously shifting is unbelievably aggravating. I'm dealing with it on my new work truck too.

I still like my '95 K2500 6.5 diesel Suburban, especially with the brand new AM/Gen upgraded engine I installed in July. I just got 12 mpg towing the 24 foot trailer with my SD in it to upstate NY. That was 2 MPG higher than the old engine. :-)
