DH started working in FL and we lived in a Corp Apt. Then bought a 5er and switched to full timing. Knew we didn't want mail coming to the campground, so we opened a UPS Store box. DH changed the address on his FL DL to UPS Store address and they asked for a physical address. So he gave them the CG address.
It's a little different now because of HL security restrictions, but he can vote in FL and all tags are FL. We haven't lived in FL since 2005, he works in multiple states, pays their state taxes except when we're between projects.
