That is one of those questions that can be hard to answer. It can vary with the way one drives and the condition of the vehicle your driving and the weight you are carrying. You can begin as low as 4 mpg and end as high as 12.
Total weight is 19,000 lbs. combined. Run 60 MPH. Mostly level roads. Looking for someone who has owned a diesel pusher with the Allison 4 speed. Thanks
