With Flying J you also still get the cash price with a credit card as well as the 1 cent RV discount. In places like AZ where truckers pay 8-9 cents more than RVers you get this discount (tax reduction) as well as long as you swipe your RV card first.

Not in all states. I can think of two where there is tax at the truck pumps and not at the car pumps.

Yes, the taxes are there but you don't have to pay them. There are there in AZ but you don't pay them. They are not there in OR but you do pay them (an extra .24/gallon!). The taxes are based upon the vehicle into which they are pumped and not the particular pump that is used. The only exception I am aware of is in IN but cars and RV's are not allowed to use the truck pumps.
