Flying J/Def fluid pump
Does Flying J have a DEF fluid pump at the RV island?

Well, the math is off a little in this thread. If you can get one thousand miles per gallon of DEF then he isn't towing, I get approx. 300 miles per gallon so that changes the equation quite a bit, the 6.7 is a hog when it comes to DEF. It doesn't get the mileage most people claim either. Lol
