Never gone inside using the rv plus card. Works every time at the rv pump lanes and car lanes. Can't attest for the truck lanes as we don't have diesel. I did go inside once to get a coffee and the clerk asked if I had a loyalty card and I told them I had the rv plus card. He said it would work and scanned the card and it gave me a discount on the coffee.
I haven't looked at the Visa card. I have looked at my banks cards for the cash back/rewards options on gas and groceries, but they are only really good for the first 6 months. I've heard there are others out there are better. I may look around some more.
