Loc,
What did the flyer say about fueling at the RV pumps? Presently, paying with a CC FJ will give you the cash price + .01/gallon off @ the RV pumps if you have a rewards fueler card, and you don't have to spend money inside. I know that fueling at the RV pump is a pain, but I think that's what FJ wants us to do. It is also cleaner (less diesel to walk thru) around the RV pumps than the truck lanes.
Just my .02
