Pilot Flying J question

we have the RV Plus card and love it. We opted to have it taken right out of our checking account. This gives us a $2,000 limit. If we use it up we just pay and are ready to go. We have had the card since 2009 and have never had a problem with them. We get a email a week ahead of them taking it out and the amount has always matched. If you don't have them take it out of your checking automatically they give a $1,000 limit. You can talk to them and get a higher limit either way. I look at their website and figure out where I can save the most in our route. We are deluxe members and get 7 Cents off the cash price. We use the truck lanes, pull in fill up and go.
