Racine96ExplorerNov 22, 2013Diesel mpgQuestion: those of you who use a diesel truck to pull an RV, what kind mpg do you get when you pull your RV?
jimw606ExplorerDec 07, 2013I had a 2003 F250 7.3, towing a 10,000# fifth wheel. I calculated every tank fill up when towing.I never was below 10 and just above 14 with an average of around 12. Many things enter into mileage.
