Update:
When I received the email this morning, I replied, telling them that we were fulltime RVers with AK drivers licenses and a TX billing address, in addition to the CA ship-to address. I told them that I wasn't going to send that sensitive financial information over email.
I just received a reply from them:
Ok Dave,
Sorry about the inconvenience. I will go ahead and release the order to ship to the California address.
