Can RVers get the cash price for diesel at Flying J/Pilot?

We have the Pilot/FlyingJ plus card. We always use the truck lanes. They fill faster than the rv lanes. We have them take it out of our checking account so we have a 2500 dollar limit, otherwise you get a 1,000 dollar limit. If we hit the limit we just pay the bill and are good for another 2500. We get 7 cents off the cash price.
