Voting by mail when you live in an RV: South Dakota, Texas and Florida

Full-timers and snowbirds often get their ballots at a mail-forwarding address in South Dakota, Texas or Florida. That works only if you are already a legal voter in that state — and if the ballot reaches you in time to mark it and get it back. This page covers what each state’s election offices publish about registration, absentee or vote-by-mail requests, and where the ballot is mailed, checked on 15 Oct 2026. It is not legal advice. Residency for voting is separate from having a mailbox. Confirm every deadline and address rule with your county election office before you rely on it.

The short version. A commercial mailbox can often be a mailing address for election mail, but it is not automatically where you “live” for voter registration. South Dakota, from 1 Jan 2026, treats a registration that lists only a mail-forwarding, CMRA or PO box address (with no description of where you actually live) as a federal-only voter. Florida’s Division of Elections has said mail-forwarding customers who never lived in the county are “most likely not legal residents.” Texas lets many travelers vote by mail if they will be out of the county, and then the ballot must go to an address outside that county. Ballots are time-sensitive — ask your forwarder how they handle election mail; don’t invent a guarantee.

Residence vs mailing address Registration / absentee forms ask for where you live and a separate mailing address if different. If the residence line is only a CMRA, mail forwarder or PO box with no habitation description, you are a federal-only voter (from 1 Jan 2026). Voter registration wants a residence address, not a PO box or business. If there is no street address, describe where you live and list a separate mailing address. Mail ballots generally go to residence or mailing address; “absent from the county” requires an out-of-county mailing address. Voter registration form: “Address Where You Live (legal residence—no P.O. Box)” plus optional mailing address if different. Vote-by-mail ballots go by nonforwardable mail to the mailing address on file or another address you request in writing.
Who can get a mail ballot Any registered voter may request an absentee ballot (no excuse listed on the SOS absentee page). Limited grounds: 65+ on Election Day; sick or disabled; expecting to give birth within three weeks before or after Election Day; absent from the county during early voting and Election Day; confined in jail (if otherwise eligible); or civilly committed under Ch. 841, Health & Safety Code. Any registered voter may request a vote-by-mail ballot (no excuse required on the Division of Elections page).
Request deadline (2026 general, Nov 3) Apply up to 5 p.m. or end of regular office hours (whichever is later) the day before the election. Absentee voting for the general began 18 Sep 2026. Voted ballot must reach the county auditor before polls close on Election Day. ABBM must be received (not just postmarked) by the Early Voting Clerk by Friday, 23 Oct 2026 (11th day before Election Day). Request that a ballot be mailed by 5 p.m. on the 12th day before the election (for Nov 3 that is 22 Oct 2026). Supervisor mails within 2 business days after a request, no later than the 10th day before. Voted ballot must be received by 7 p.m. Election Day.
CMRA / forwarder as mailing address for the ballot Absentee form has a separate mailing-address section. Using only a forwarder as the residence address without describing habitation → federal-only status. If your ground is absence from the county, the ballot must be mailed outside the county — a forwarder outside the county can fit that role if the clerk accepts the application. Confirm with your county. You may request mailing to an address other than the one on file with a signed written request (Form DS-DE 160). Ballots are marked “Do Not Forward,” so USPS will not chase you — the address on the request has to be right.

Not legal advice — check your county

Election rules are run at the county level even when the Secretary of State or Division of Elections publishes statewide forms. Deadlines, drop boxes, and how a clerk reads a PMB address can differ. This page summarizes public state pages checked tonight. It does not tell you whether you are a resident, how to fill out a form, or how to beat a deadline. Ask your county auditor (SD), Early Voting Clerk (TX), or Supervisor of Elections (FL). For the bigger domicile picture (license, title, jury), see RV domicile: SD vs Texas vs Florida.

South Dakota

Residence for registration

Under SDCL 12-1-4 (effective 1 Jul 2025), a “resident” for elections is someone who keeps an actual fixed permanent dwelling or other abode where they live and usually sleep for at least 30 consecutive days. You stay a resident while away if you intend to return. You can be a resident of only one place.

From 1 Jan 2026 (SDCL 12-4-1.3), if you apply to register or to vote absentee using only the address of a commercial mail receiving agency, mail forwarding service, or other post office box as your residence address, without describing where you actually live, you do not meet the state’s residency test for Title 12 and may be registered only as a federal voter. That ballot lists U.S. President / electors, U.S. Senate and U.S. House — not state or local races. The SOS registration page and the official absentee request form both warn about this.

The absentee request form (ARSD 5:02:10:01, effective 1 Jan 2026) says: write your voter registration address and/or describe where you live; if your address is a CMRA, mail forwarder or PO box (or you have no street address), describe the physical location in writing or with a map. There is a separate mailing address section if different from the registration address.

How to get and return an absentee ballot

Texas

Residence for registration

Texas voter registration wants your residence address — not a PO box or business address. If your home has no street address, you describe where you live and give a separate mailing address. That mailing line is where many RVers put a forwarder; the residence line still has to describe a place you live. Confirm details with your county voter registrar and the current application.

Who can vote by mail

Texas does not offer no-excuse mail voting. Per VoteTexas.gov eligibility, you must qualify under one of these grounds:

Full-timers who will be out of their Texas county on those dates often use the absence ground. VoteTexas.gov says that when absence is the reason, the ballot must be mailed to an address outside the county. A mail forwarder outside that county can be the place the ballot is sent — if your Early Voting Clerk accepts the Application for Ballot by Mail (ABBM). Do not assume; ask the clerk.

Deadlines and where it goes

Florida

Residence for registration

The statewide voter registration application (DS-DE 39) asks for “Address Where You Live (legal residence—no P.O. Box)” and a separate mailing address if different. A commercial mailbox is not a legal residence by itself.

Division of Elections opinion DE 18-09 (19 Jun 2018), answering Clay County about a private mail-forwarding service used by RVers and cruisers, concluded that customers who try to establish residency with a Declaration of Domicile and/or Florida license tied to the mail service, but who have no past or present physical presence and intent in the county, are “most likely not legal residents” for voter registration. A commercial mailbox cannot be a legal residence; a Declaration of Domicile and a license alone do not prove one. That opinion is still the Division’s published guidance on this fact pattern. Read the full PDF and talk to your Supervisor of Elections about your facts.

Vote-by-mail requests and mailing

Getting the ballot through a mail forwarder

Ballots are official, deadline-driven mail. A few practical points from state pages and provider pages checked tonight — without inventing service-level promises:

App-style network mailboxes (Traveling Mailbox, iPostal1, Anytime) are useful when you mainly want scans and are not trying to hang domicile-state voting on the address. For domicile-state ballots, prefer an RV-oriented forwarder in the state where you are actually registered, and still verify the address rules with the county. Network links when that job fits: Traveling Mailbox, iPostal1.

A simple checklist before election season

  1. Confirm you are registered in the county you think you are — use the state voter lookup (SD Voter Information Portal; Texas and Florida county / state lookup tools).
  2. Read the domicile guide so license and voting stories match.
  3. File the absentee / vote-by-mail request early. Build in days for the county to mail the ballot, days for the forwarder to receive and remail it, and days for you to mark and return it.
  4. Tell your forwarder, in writing, that a ballot is coming and how you want it handled.
  5. Track the ballot (Florida and many counties offer status lookup; USPS Informed Delivery can flag the outer envelope).
  6. Mail the voted ballot early enough that the county receives it by the Election Day deadline — not just that you dropped it in a blue box.
