Just completed a 3100 mile round trip to Durango, CO, Rally in the Rockies, towing two big Harleys in my toy hauler. Averaged 11.3 MPG at 65 MPH. Fuel prices varied from 2.69 to 3.29 per gallon. RV loaded weight was 10K lbs.Tranny and water temps normal at all times. Truck and RV performed flawlessly except for cooling fan which seemed to run at times for no reason at all. Good trip all around.
