I had problems with one of my credit cards when we first started fulltimeing. After they placed a hold on it I explained what we were doing and that we would be traveling all over the USA. I have not had a problem with the card company since, they have learned over time the way we move about. Last Spring as we traveled north someone in GA acquired my CC number, I was contacted about several small charges made a few weeks after we had passed through none were made by me. They knew by fuel charges we were well out of that area and I never charge small amounts, under $10. They cancelled the card and sent a new one.
