My first F250 had a 27 gallon tank (short bed). I did get 10-11 mpg towing (I love diesels), but I had to make sure there was a truck stop every 200-225 miles. My current truck has a 37.5 gallon tank and a 60 gallon auxiliary. 97 gallons means I can get to the Fort (1003 miles) in 1 stop. I figure it saves an hour drive time not having to make 3-4 stops for fuel.My F150 I was using for towing at the time had a 25 gallon tank. We found ourselves stopping once every 180-200 miles.
