rusw1, take it to dealer and check for updates for your truck. How much lift do you have? The higher, the less fuel mileage. Your tire size will affect mileage if you can't get moter to 'sweet spot' while towing. About 1600 rpm's. While towing, you should be in the 12-14 range unless your trailer is VERY tall.
