Healthcare.....
If under 65 and not using Medicare then you will need to research medical insurance/coverage
And that will be tied to your 'domicile' state
Check out TX and FL for FT residency and medical coverage
If 65/older and Medicare then you have more options for 'domicile' state
Domicile state is your official residency where DLs, Vehicle registration (and Insurance), Voting, Medical and MAILING address will be.
Mailing address......
Via a mail forwarding service
SO go paperless as much as possible and switch to on-line banking
And downsize your stuff.
LESS is More
Have an 'exit' plan just in case you don't like FT lifestyle, you need to go stationary due to health reasons or family issues
