Can't beat the 8.1 Allison combo for pulling and towing. Ride is rough. I had electrical problems. It would just die and fail to restart for 5 min. to 3 hrs. then run fine. Never did get it resolved.
LT package is best of all brands for comfort and features. Chevy leather seat blow the competition away. Ford ride is softer but seat are lacking comfort. 8.1L and allison is awsome combo if you pull a trailer daily.
