Why Domicile Matters When You're Full-Timing
When you go full-time in an RV with no permanent home, you still need a legal domicile — a state of residence — for your driver's license, vehicle registration, voting registration, bank accounts, health insurance, and income taxes. Many full-timers don't think about this until they're already on the road and dealing with expired licenses and registration issues. Plan before you leave.
The good news: you get to choose your domicile state, and the three most popular choices for full-timers — South Dakota, Texas, and Florida — all offer significant advantages over most other states.
The Three Domicile States Full-Timers Choose
South Dakota: The most popular full-timer domicile for good reason. No state income tax. Driver's license obtainable in one day with physical presence (no residency waiting period). RV registration available quickly. One of the lowest total cost-of-ownership states for vehicle registration. Mail forwarding services in Rapid City and Sioux Falls serve the full-timer community. The main challenge: South Dakota requires you to actually be physically present to get your first license — a trip to Rapid City is required.
Texas: No state income tax. Large full-timer community means services are well-established. Vehicle registration is reasonable but not as inexpensive as South Dakota for larger RVs. Texas requires in-person presence for registration and driver's license. A good choice if you already have connections to Texas or plan to spend winters in the Rio Grande Valley (already a huge snowbird destination).
Florida: No state income tax. Warm climate aligns well with snowbird and winter full-timing patterns. Vehicle registration in Florida is tied to vehicle weight and can be expensive for heavy motorhomes. Mail forwarding services are well-established in Pensacola, Bushnell, and other full-timer hubs.
Setting Up Your Mail System
You need a physical mailing address — not a PO Box — to establish domicile and receive mail that carriers won't send to a PO Box (including IRS documents, jury summons, and most government mail). Three main approaches:
Mail forwarding services: Specialized companies provide a physical address and forward your mail on a schedule you control. Most offer scanning — you review your mail in an online dashboard and choose what to forward, discard, or open/scan. Costs range from $15-$30/month for basic service to $50+/month for full-service forwarding. Well-known services catering to full-timers: Escapees (Livingston, TX), America's Mailbox (Box Elder, SD), MyDakotaAddress (South Dakota), St. Brendan's Isle (Florida).
Family member's address: Simple and free — use a trusted family member's home as your address. Downsides: burdens the family member, creates a tie to their state (which may not be the tax-favorable state you want), and makes them responsible for your important mail.
Friends in the desired domicile state: If you have trusted friends in South Dakota, Texas, or Florida willing to receive your mail, this works — with the same caveats as using family.
The Mail Forwarding Process in Practice
Most full-timers on mail forwarding services develop a rhythm: check your mail dashboard weekly. Forward a batch every 2-3 weeks when staying in an area long enough for mail to arrive. For time-sensitive mail (checks, government documents, prescriptions), most services offer overnight forwarding for an additional fee.
Tips for reducing mail volume before going full-time: switch everything possible to paperless billing and statements (bank, credit cards, utilities during sell-down, investment accounts). Cancel magazine subscriptions or switch to digital. Notify government agencies (IRS, Social Security, Medicare) of address changes to your mail service address early.
Vehicle Registration as a Full-Timer
You must register your RV and tow vehicle (or toad) in your domicile state. This means transferring plates from your previous state when you establish domicile. South Dakota has a streamlined process for this — many services in Rapid City handle the DMV paperwork on your behalf for a service fee (worth it for the time savings).
Annual registration renewals are typically handled by mail or online — you don't need to return to South Dakota each year once you're established. Keep your domicile state's physical inspection requirements in mind — South Dakota doesn't require annual vehicle inspections, which is another reason it's popular.
Health Insurance for Full-Timers
Health insurance is the most complex piece of the full-timer financial puzzle. Your options depend heavily on your age, employment status, and income:
- Under 65, employed remotely: Employer-provided health insurance typically travels with you. Verify your plan's network covers out-of-state care.
- Under 65, self-employed or unemployed: ACA marketplace plans through healthcare.gov. Look for plans with nationwide PPO networks rather than HMO plans tied to a local network. Your domicile state determines which plans are available to you.
- 65+: Medicare covers you nationwide — this is why many retirees find full-timing financially simple from a health insurance standpoint. Supplement plans (Medigap) add nationwide coverage for the gaps Medicare leaves.
- Medically dependent: If you have ongoing specialist care, full-timing requires advance planning to find telehealth solutions and occasional return visits to specialists.
