2013 GMC Denali 2500:
Pros: Tons of power going up hills, exhaust brake down hill, only touch the brake once. Allison is perfect. Great factory tow mirrors and brake control. Every creature comfort.
Cons:......I worry a little about the injection system croaking...thought(hoped) maybe I'd get 15mpg towing.....I get 12mpg normally
