Will be heading south starting next weekend. This will be my first trip with the new coach that needs DEF. Does anyone know which fuel stops along I95(Petro, Flying J, Loves, etc) have DEF pumps and are they accessible for RV's? The DEF tank on my Forest River Berkshire is in a compartment where the door lifts upward. Looks like it would be a real hassle to try to pour DEF into the tank from a container.Thanks.

Every Flying J/Pilot had a DEF nozzle at each diesel pump. It even asks you if you need DEF so it can put it on the same bill. I have to move my rig because my fuel fill is toward the front and the DEF fill is toward the back but the pump understands.Looks like I get 1K+ miles on a DEF fill. Between 8.5 and 10 mpg on diesel.Good Luck!

I use about 2.5 gallons of DEF for every 100 gallons of diesel fuel, or about 1 Gal DEF for each 40 gals diesel.

Here is a easy DEF calculator.http://www.cumminsfiltration.com/html/en/products/fuel/diesel_emission/def_calculator.html

How much does DEF run at a truck stop? I have been paying $4.79/ gallon at Walley World in a 2.5 Gallon container. I kind of like to fill the 13 gallon tank at home before heading out so that it is one less thing to worry about but I might be paying too much.

Last time I fueled at J it was 2.99 per gallon..I don't use it but I looked anyway...
