We have taken long trips over the years, but are now going full-time. Sold home in CA and plan to use SD as our domicile for a couple of years at least. We are Medicare recipients who use an HMO. We have looked into Medicare Supplements, but Wow, they are expensive. Would rather keep our HMO plan. How do you-all handle this when full-timing? We are OK for the next 6 months with our current CA health provider, but then must choose a new group/health plan. Are we stuck with choosing one in SD, even though we won't actually "live" in SD? Thanks for any and all input. Happy Trails.
