I spec'd this out for my husband after extensive research. We have a small hot shot business and needed a powerful, yet reliable truck to pull goose neck flatbed trailers. The 6.7 L Cummins was the big draw. I did order the truck with some aesthetic touches that made it easy on the eye and set up good for long drives. We had the problem with the emission light coming on frequently, but that is resolved now. Pulls loads up to 9000 lbs without even knowing it is back there, including through the mountains of VA. In LOVE with the truck and it draws gawkers everywhere my husband goes to deliver loads. Other than the fuel mileage, it is AWESOME.
Power, extremely quiet engine, interior room, comfortable seats for tall people, back seat is like a living room, room behind back seat, heated seats, solid feel, separate ac controls, sharp looks.
