Bought my truck new with the Cummins diesel. It pulls my 32 ft fifth wheel easily. I get 17 around town and 22 0n the hwy. Pulling the trailer I get 9 to 12 MPG. Does wonder and good power. Transmission worked on once for rebuild at 60,000 and sensors at 135,000. Love driving it cross country.
Power, comfort and space.
Should be lower for fifth wheels and a more reliable transmission.
