Pretty slick truck. Chirps tires in second and holds its own against most other trucks and cars. Pulls my trailer and all my stuff out to the lake with no questions asked. Drives down cutlines pretty good most of the time (All -terrains) and rides super quiet down the highway. Rides smoother than my dads new duramax. Starts everytimein the cold. All while getting a manageable 15-18 miles per gallon.
