Thanks to everyone for the references and kind words.
@TXiceman make a good point that it hard to make a recommendation knowing so little about our situation. In brief, we intend to spend a month or so each winter around Bushnell when we will take care of things like doctor and dentists visits. We’ll likely find ourselves on a BlueCross/BlueShield ACA plan of some kind. We’re fortunate to be in good enough health that an annual physical and infrequent screening procedures should be all we require. That of course won’t be true forever, but we’ll cross that bridge when we get there.
Incidentally, I do see that most community members seem to domicile in Texas and not Florida. We’re inclined to use Florida as a home base because it has far better weather in the winter months and it is closer to family (still out-of-state, but much closer than Texas is).
