Many full-timers have their residencies established in S Dakota, Florida and Texas. There is no requirement that we spend any certain number of days in the state. All 3 states are full-timer friendly and have established rules if you travel. We are originally from MI and know that we do not ever want to own a house there again. If we were to purchase, we would purchase land that we could park our RV on in the summer months when it's warmer and then head south for winter. IL also has high property tax, insurance, other taxes, registration fees that will likely just keep getting higher. I would choose a less expensive state for home base and then travel wherever you want.
