Nina did a great job on this. We will be caught in this mess come the end of December when I "officially" retire from my full time career. We also spoke with Kyle Henson and it looks like we will be getting short term insurance so that we have coverage from Jan. 1. This gives us time to start the process of switching to become a Texan, especially since we have to switch all of our addresses, etc. before June which is due to Dakota Post (Alternative Resources) in Sioux Falls has switch to a new facility.
As Nina pointed out, anyone younger than 65 and looking to become full time RVers, do not even consider SD, go straight for Texas or Florida. As we have come to find out, none of the mail forwarding services are doing any advocacy for RVer's on this issues nor do any of the politicos care as they have basically stated they have left it up to the insurance companies to work it out.
