This truck is a very nice truck. I'm a bit disappointed in the fuel mileage after the last outing of 350 miles. Maybe the mileage is very good, but I was really hoping for better with a small block diesel. Straight highway, empty. I went approximately 50 miles for every speed increase to let the onboard computer AVG MPG settle (I have found after 3500 miles, it's very close +/- 1MPG. I was getting: approx 23-24MPG @ 55MPH, 21MPG @ 65MPH, 19MPG @ 75 MPH. The MPG dropped almost on the button 1 MPG for every 5 MPH faster. I topped of the tank to start and and retopped off the tank to verify. The onboard computer was accurate. I was hoping for 20-30% better out of a diesel. Weight ~empty: 7350 (on scales).
