Every full-time RVer in the United States is required by law to maintain a legal domicile - the state you officially call home for purposes of vehicle registration, driver's licensing, voting, and taxes. Because an RV isn't a permanent address, choosing your domicile state is a deliberate decision rather than a default one.

Three states have become popular among full-timers for their relatively straightforward domicile processes and absence of state income tax: South Dakota, Texas, and Florida. Each allows residents to establish domicile without owning or renting traditional real property, typically through a commercial mail service address or a campground stay combined with a signed affidavit of intent.

Your chosen state will affect your vehicle registration costs, insurance rates, and income tax exposure - so it's worth researching each carefully. Consult a tax professional or attorney familiar with itinerant living before finalizing your choice, since individual circumstances vary significantly.

States with no personal income tax Includes SD, TX, FL (among others) (IRS and state revenue agency records)
Primary mail solution used by full-timers Commercial mail forwarding service (Widely reported across RV lifestyle communities)
Biggest healthcare challenge Network coverage tied to geographic regions (ACA marketplace plan structure)
Key domicile documents typically required Affidavit of intent, mail service address, brief state visit (State DMV and residency requirements vary)

Managing Mail on the Road

Without a fixed address, mail becomes a genuine operational challenge. Most full-timers rely on one of three approaches:

  • Commercial mail forwarding services - Companies specializing in RV and nomad clients assign you a real street address, receive your mail, scan envelopes digitally, and forward physical pieces on request. This is the most common and flexible solution.
  • Trusted family or friend address - Works in early stages, but can burden the host and create complications if you change domicile states.
  • USPS General Delivery - Mail sent to a town's main post office, held for pickup. Useful for occasional packages but impractical as a primary system.

When selecting a mail service, look for one that offers digital scanning so you can review mail remotely before deciding what to forward - reducing unnecessary shipping costs. Set up electronic billing and statements for as many accounts as possible to reduce physical mail volume altogether.

Go Digital Wherever Possible

Switching bank statements, utility bills, and government correspondence to electronic delivery significantly reduces the volume of physical mail you need to manage. The IRS, Social Security Administration, and most financial institutions all support paperless options. Starting this process before you hit the road makes ongoing mail management far simpler.

Accessing Healthcare Without a Fixed Address

Healthcare is frequently cited as one of the most complex logistics challenges for full-time RVers, particularly for those not yet eligible for Medicare. The core problem is that most employer-sponsored and marketplace health insurance plans are structured around networks tied to specific geographic regions - which creates real gaps for someone moving across state lines regularly.

Domicile

Your legal state of residence for government and tax purposes. For full-time RVers, this is a chosen state rather than where you physically spend the most time.

Mail Forwarding Service

A commercial service that receives physical mail on your behalf at a fixed address, scans it digitally, and ships selected pieces to wherever you currently are.

PPO (Preferred Provider Organization)

A type of health insurance plan that allows members to see out-of-network providers at higher cost, offering more geographic flexibility than HMO plans - important for travelers.

Health Care Sharing Ministry

A membership organization in which participants share each other's medical costs. These are not regulated as insurance and carry different protections and limitations than standard health plans.

USPS General Delivery

A postal service that holds mail at a local post office for pickup by the addressee. Useful for travelers passing through a town but not a reliable primary mail solution.

Common approaches full-timers use include:

  • ACA marketplace plans with nationwide networks - Some insurers offer PPO-style plans with broader national coverage. Availability varies by domicile state, so this is another reason domicile choice matters.
  • Health care sharing ministries - Not traditional insurance, but cost-sharing arrangements that some full-timers use. These carry significant limitations and are not regulated as insurance; research carefully before relying on one.
  • Telehealth services - Can address routine care and prescription management remotely. Useful as a supplement but not a replacement for in-person care.
  • Urgent care and community health centers - For non-emergency in-person needs while traveling.

Full-timers with chronic conditions or ongoing care needs should factor healthcare access heavily into their planning.
