Great styling. Denali honeycomb grille is undeniable. 20 inch polished aluminum wheels, and chrome running boards. A powerful 6.6 liter Duramax Diesel engine with 395 hp. coupled with a super reliable Allison six speed transmission putting down 765 ft. lbs. of torque are what moves this beast down the road. Even with a load behind you. This 3/4 ton beast is boasting a max payload of 6635 lbs. and a towing capacity of 21,700 lbs.
Story
Driving along the beach highway with the sunroof open and windows down taking in the salt air.
Pros
Powerful diesel engine, reliable Allison transmission, rear entertainment system, navigation, XM radio, Bose surround sound speakers, leather interior, heated and cooled seats, dual zone climate control, four wheel drive, fuel mileage, running boards, remote start, high towing capacity, exhaust brake, high fuel capacity, large cabin, center console, USB port, 3,12 volt power outlets, 6 way power seats, sunroof.
Cons
Rear park assist constantly says it's blocked while connected to a trailer, does not come with factory tow mirrors, AM radio goes in and out constantly, glow plugs are prone to fail, DPF system takes costly DEF fluid, electric seat motors are prone to failure, traction control is tied to multiple electronic devices and is hard to trouble shoot when there is an issue, belt tension pulleys are made of cheap plastic.
