Medicare doesn't care where you are as long as you are inside the USA. The supplimental plans ...well, some of them have covered service providers...and you have to go there. But, you can get insurance good for anywhere.
As for Medicaid...that is State dependent.
As for my question....it sounds like I should just keep Florida. No one seemed the know of a western state that has all my requirements.... no income tax, no Vehicle inspections, easy to get documentation for DL, etc
Every 5 years have to plan a long trip.....
