So sorry for your loss. I completely understand. Do not lose faith about the election. There's still a long way to go before the results are certified. Trump has the best legal team going. Once the fraud is exposed and remedied, I'm confident of FOUR MORE YEARS!
Every American citizen must have a "physical" address. Full-time travelers can choose their "domicile" state if they don't have a permanent residence. The procedure for establishing residency varies from state to state. Once completed, you have a "physical address" which may never be used for anything other than banking, voting and calculating insurance rates. As for receiving mail, full-timers use mail-forwarding services. It's perfectly normal to have both a "physical" and a "mailing" address.
