If you live in an RV full-time, the address you use on official paperwork is a street address in the state you’ve chosen as your legal home, almost always provided by a commercial mail forwarding service in that state. That single address becomes the anchor for your driver’s license, vehicle registration, voter registration, tax returns, banking, and insurance. Picking it is really two decisions stacked together: which state you want as your domicile, and which mail service inside that state will give you a usable street address.
Why a Mailing Address Isn’t Enough
The address question for full-timers gets confused because people treat “where my mail goes” and “where I legally live” as the same thing. They aren’t. Domicile is your one permanent legal home, the state you claim as your own and intend to return to. You can only have one at a time. Residency just means where you happen to be physically located, which for an RVer changes constantly.
Domicile controls the expensive questions: which state taxes your income, where you vote, where your vehicles are registered, and where you can be summoned for jury duty. A mailing address alone doesn’t answer any of those. What you need is a street address inside the state you’ve chosen as your domicile, used consistently on every official record. Vague or inconsistent paperwork is how people end up paying income tax to a state they thought they’d left, or having an insurance claim questioned because the documents don’t match the reality.
Choosing Which State to Use
Three states come up constantly among full-time RVers: South Dakota, Florida, and Texas. None levies a state income tax, so retirement withdrawals, Social Security, and remote-work income aren’t taxed at the state level. Each has a large RV community and established services built around domicile for travelers.
South Dakota has the lowest barrier to entry. The state accepts a one-night stay at a campground or hotel, documented with a receipt, as proof of physical presence when applying for a driver’s license. You still need a local street address, which most RVers get through one of the mail forwarding services headquartered there. Florida and Texas offer similar tax treatment with their own quirks around vehicle registration costs, insurance rates, and inspection requirements, so the cheapest option depends on your rig and your situation.
Price isn’t the only factor. Think about where you’ll realistically spend time, whether you have family or medical providers nearby, and whether the state’s rules on things like vehicle inspections work for your travel pattern. Unwinding a domicile later and switching to a different state creates its own paperwork headache, so it’s worth getting the choice right the first time.
Getting a Street Address You Can Actually Use
A commercial mail receiving agency, usually called a CMRA, is the backbone of most full-time RV addresses. A CMRA gives you a real street address rather than a P.O. Box number, which matters because most agencies won’t accept a P.O. Box for a driver’s license, vehicle registration, or similar records. The service holds your mail, scans it, or forwards it to wherever you’re parked.
Setting one up requires USPS Form 1583, which authorizes the agent to accept mail on your behalf. You’ll need two forms of ID: one government-issued photo ID such as a passport, driver’s license, or military ID, and a second document confirming your address, such as a vehicle registration card, current lease, or voter card. A state-issued driver’s license can count for only one of the two, not both. You sign the form either in person at the CMRA, via a live video call with the agent, or before a notary public.1USPS. Application for Delivery of Mail Through Agent (PS Form 1583)
Monthly fees generally start around $10 to $15 and climb to $30 or more for premium addresses or added features. Most services bundle mail scanning, package receiving, and junk-mail filtering, with per-page and package handling charges on top. Compare total cost rather than the base rate.
One quirk to know about: the USPS requires CMRA addresses to include “PMB” or “#” before your box number, which signals to anyone familiar with the format that it’s a forwarding service. In practice, most RVers report few problems using a CMRA address on official documents, especially when the driver’s license shows the same address. Occasional pushback from a bank or other institution usually clears up with a quick explanation.
P.O. Boxes
A USPS P.O. Box works for general mail but can’t substitute for a street address on a driver’s license, vehicle registration, or most other official records. If you already have a CMRA address, a P.O. Box adds little.
General Delivery
If you’re passing through a town and need to receive a specific piece of mail, USPS General Delivery lets you pick it up at the local post office without an account. The post office holds each piece for up to 30 days unless the sender requests a shorter window. At offices with letter-carrier service, mail without specific instructions is held just 10 days. General Delivery is available at only one designated facility per post office area, and it’s a safety net for one-off situations, not a permanent address.2USPS. What Is General Delivery?
A Friend or Family Member’s Address
Using a trusted person’s residential address is the cheapest option. It works best when that person lives in a state you’d choose as your domicile anyway. The downsides are practical: your contact has to sort and forward mail regularly, sensitive documents pass through their hands, and some institutions ask questions when your name doesn’t match the utility bill at that address. Some states accept a signed affidavit from the homeowner confirming you live there for driver’s license purposes, but the specifics vary. Make sure the arrangement is genuinely workable long-term before relying on it.
Making the Address Stick Across Every Record
Picking a state and getting a street address are only the first steps. Making your domicile stick requires a trail of official actions that all point to the same place:
- Get a driver’s license issued in your new state, and surrender the old one.
- Register your RV and any towed vehicles in the new state.
- Register to vote at your new address.
- Open a bank account using the new address, or update your existing accounts.
- File federal and state taxes using the new address.
- Establish a primary care provider in the state if you can.
No single action locks in your domicile. Courts and tax authorities look at the full picture: where you vote, bank, see a doctor, and say you intend to return. The more connections pointing to one state, the harder it is for a different state to claim you. Leaving loose ends in your old state (an active driver’s license, a voter registration, utility bills in your name) is exactly how people end up in disputes.
Banking has its own federal wrinkle. Every bank must collect a residential or business street address when you open an account. A standard P.O. Box alone won’t satisfy the requirement for an individual, though the regulation does allow an APO or FPO box, or the street address of a next of kin or other contact person.3eCFR. 31 CFR 1020.220 – Customer Identification Program Most full-timers use their CMRA street address or a friend’s address. The regulation doesn’t explicitly say whether a CMRA address qualifies, but because CMRA addresses look like standard street addresses, they’re widely accepted. Consistency across your license, bank, and mailing records is what keeps the questions short.
Insurance: Don’t Lie About Where the RV Lives
RV insurance policies ask for a “garaging address,” meaning the place where the rig sits when you’re not driving it. Insurers use that location to assess theft rates, weather exposure, and accident frequency. For a full-timer, the rig is always in use and “where it sits” changes every few days.
If you tell your insurer the RV is garaged at a specific residential address while you’re actually living in it full-time across the country, that’s a material misrepresentation. An adjuster who discovers the discrepancy during a claim investigation has grounds to reduce or deny coverage. The fix is straightforward: tell your insurance company you live in the RV full-time. Several insurers specialize in full-time RV policies. You’ll typically provide your domicile address as your home address, your CMRA or forwarding address for correspondence, and a garaging address that reflects where the RV spends most of its downtime.
Watch Out for Your Old State
If you moved from a state with an income tax to one without, your former state has a financial incentive to argue you never really left. States with income taxes regularly audit former residents who claim to have changed domicile, and losing that audit means back taxes, interest, and penalties on years of income you thought was tax-free.
Common triggers for scrutiny include:
- Spending more than 183 days in the old state during a calendar year, which many states treat as a residency threshold.
- Keeping a driver’s license, voter registration, or utility accounts open in the old state.
- Maintaining a home, storage unit, or business connections there.
- Social media and credit card records that show frequent time spent in the old state.
The strongest defense is thorough documentation. Keep a travel log showing where you parked each night. Make sure every official record points to your new domicile state. Tax advisors who work with full-time travelers suggest completing the full switch at least 12 to 18 months before expecting your position to hold up to an audit, because states look at the chronological record of when you actually moved your life, not just when you filed a change-of-address form.
Jury Duty Comes With the Territory
Having a domicile somewhere means you’re eligible for jury duty there. For federal courts, you must have lived primarily in the judicial district for at least one year to qualify. State and county rules vary, but most pull jury pools from voter registration rolls or driver’s license records, the same documents you filed when setting up domicile.4United States Courts. Juror Qualifications, Exemptions and Excuses
If a summons arrives while you’re parked two thousand miles away, courts allow requests for deferral or excusal based on undue hardship. In counties that host popular RV mail forwarding operations, the clerk’s office handles these requests routinely. But domicile doesn’t exempt you from the obligation. Ignoring a summons can bring fines or a contempt finding, so respond promptly even if you plan to request an excusal.4United States Courts. Juror Qualifications, Exemptions and Excuses
