My 2014 Cummins SRW , I can get 19 to 20 miles per if I keep it at 64 or so miles an hour , manual measurement . When towing my 20 foot trailer at same speed I get 13 plus . I can go 450 miles towing if I carry a safety can of diesel, which I have never needed . Speed is the big killer of miles per .
