I have 9200 miles on my 7.3, I pulled an enclosed trailer to Dallas and back was running about 70 mph I was getting 9.8 miles to the gallon , pulling a 82 inch wide by 16 foot long flat bed trailer was a John Deere 1025 on it or an altoz 660I zero turn mower, I get 15.2 miles to the gallon, on a straight level stretch of highway between my house an Beebe which is 24 miles I get 16.4 miles to the gallon empty, The truck is an F350 super crew long wheelbase
And for comparison. My 02 Excursion V-10 with 3.73's and a 4 speed would do 15mpg. With 4.30's it did 14.3. Towing with 4.30's and a 5 star tune would do 7.5 towing a 35ft 9300lb 11.5ft tall trailer.
