Excellent power, relatively quiet engine, very good diesel mileage. I have hauled over 4000 pounds in the bed, and used 2nd gear to start, did not need low. Cab needs some more space, my old Ford was a lot larger, especially the back seating area. Good access to air, radio controls. It has a good strong ride, and is very easy to drive, easier than the Ford or Chevy. It turns easily with a long horse trailer. Will buy another Cummins diesel truck, if I can wear this one out.
Reliable power, mileage, good brakes
Improve and expand the cab. Give more room for back seat passengers.
