RV Plus Card

Thanks for the info. I do have a question. I have the card coming and never have used one before. But there is a flying j we use on the way to one of our favorite places. It does have a couple rv lanes to the side. We have used those lanes before, but we had a long TT and truck and couldn't fit in the other places as the truck was not diesel. We now have a motorhome which is not diesel either. Do we need to still use those rv lanes to get it to work without having to go inside? Can we use the regular gas lanes as well or will we have to go inside for those transactions?
