In most states, you can legally carry a gun in your RV, but the rules change depending on whether the rig is moving or parked, which states your route crosses, whose land you camp on, and what magazines and ammunition you bring along. A firearm that’s perfectly legal at home can produce felony charges two states over. The traveler’s job is to know which rule applies at each point of the trip.
Driving vs. Parked: The Classification That Controls Everything
While you’re on public roads, every state treats your RV as a motor vehicle, and that state’s vehicle-transport rules apply. Those rules typically dictate how the gun must be stored, whether it can be loaded, and whether you need a permit to keep it accessible.
When you park, the picture can change. Many states extend Castle Doctrine protections to “temporary habitations” or “dwellings,” and a parked RV set up at a campsite can qualify. In those states, you may keep a loaded, accessible firearm inside the RV the same way you would at home, with no special permit. States that draw this line use different language, and some require the RV to be connected to utilities or otherwise set up for habitation before dwelling status applies. A handful of states treat an RV as a motor vehicle at all times, parked or not.
When you don’t know which rule your state uses, default to the vehicle rules. They’re almost always stricter, and following them keeps you legal either way.
Federal Safe Passage Under FOPA
The Firearm Owners Protection Act gives you a federal right to transport a firearm through states where you couldn’t otherwise legally possess it. Under 18 U.S.C. § 926A, you can move a gun from any place where you may lawfully possess it to another place where you may lawfully possess it, as long as the firearm is unloaded and neither the gun nor ammunition is “readily accessible or directly accessible from the passenger compartment.”1Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms In a vehicle without a separate cargo area, the gun and ammo must be in a locked container other than the glove compartment or console.
RVs complicate this because the “passenger compartment” is essentially the entire living space. A rifle under the bed or a handgun in a kitchen drawer is arguably reachable from the driver’s seat. The safest approach is to lock the firearm in a hard-sided case and stow it in an exterior storage bay or a rear compartment you can’t reach while driving. If your RV has no separate compartment, a locked container is mandatory under the statute.
Where FOPA Runs Out
FOPA covers continuous transit, not extended visits. A gas stop or a quick meal is still transit. Spending a night at a hotel, setting up camp, or sightseeing in a restrictive state can void the protection. Courts have not been consistent on exactly how much of a stop breaks the “continuous” requirement.
The practical risk is bigger than the legal one. States including New York and New Jersey have been aggressive about enforcing their own firearm laws against travelers who believe FOPA covers them. Local officers and prosecutors may not accept the federal defense at the roadside, which means asserting FOPA in court rather than avoiding arrest. If your route passes through a highly restrictive state, plan stops carefully and keep the firearm locked and inaccessible the entire time.
Concealed Carry Permits Don’t Follow You Everywhere
Your home-state concealed carry permit does not work in every state. Each state decides which other states’ permits it will honor. As of early 2026, 29 states have adopted constitutional carry, meaning no permit is required to carry concealed there. The remaining states require a permit, and several refuse to honor any out-of-state permit at all.
California, New York, New Jersey, Massachusetts, Hawaii, Maryland, Connecticut, and Illinois generally do not recognize permits issued by other states. Traveling through one of them with a loaded, accessible gun and an out-of-state permit can result in felony charges.
Before any interstate trip, check reciprocity for every state on the route, including states you only pass through. Official state police and attorney general websites are the most reliable sources, and agreements change often. Some RV travelers pick up non-resident permits from states with broad reciprocity, such as Florida or Utah, to fill coverage gaps.
Magazines, Ammunition, and NFA Items
Even a legal firearm can carry illegal accessories. Magazine capacity limits catch more RV travelers than any other rule. More than a dozen states and the District of Columbia cap magazine capacity, most at 10 rounds. Colorado, Vermont, and Washington allow up to 15 rounds. Delaware caps at 17. Illinois splits it: 10 rounds for rifles, 15 for handguns. In these states, possessing a prohibited magazine can be a separate criminal offense from anything to do with the gun.
If any state on your route has a limit, the simplest fix is to carry only 10-round magazines the whole trip. Locking higher-capacity magazines in a separate container doesn’t reliably protect you, because many of these laws prohibit possession outright.
New Jersey restricts hollow-point ammunition more aggressively than any other state. You can possess hollow points at home or transport them to a range or hunting site, but you cannot load them into a firearm you’re carrying. Passing through New Jersey, swap to standard ammunition or store hollow points unloaded and locked.
For short-barreled rifles, short-barreled shotguns, suppressors, and other items regulated under the National Firearms Act, interstate transport requires advance ATF approval. Submit ATF Form 5320.20 before crossing any state line with these items, and confirm the destination state allows possession.2Bureau of Alcohol, Tobacco, Firearms and Explosives. Application to Transport Interstate or to Temporarily Export Certain National Firearms Act (NFA) Firearms Failing to get approval is a federal offense, and FOPA’s safe passage does not override the NFA.
Marijuana Users Are Federally Prohibited
This is the trap most RV travelers don’t see coming. Under 18 U.S.C. § 922(g)(3), it is illegal for any “unlawful user of or addicted to any controlled substance” to possess a firearm or ammunition.3Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Marijuana remains a Schedule I controlled substance under federal law regardless of state legalization. If you use marijuana, even with a valid state medical card, you are a prohibited person federally and cannot legally possess a firearm anywhere in the United States.
ATF Form 4473, the transaction record for every purchase from a licensed dealer, warns that “the use or possession of marijuana remains unlawful under Federal law regardless of whether it has been legalized or decriminalized for medicinal or recreational purposes in the state where you reside.”4Bureau of Alcohol, Tobacco, Firearms and Explosives. Firearms Transaction Record – ATF Form 4473 Answering yes disqualifies you. Answering no when you’re a user is a federal felony. For an RV traveler who uses marijuana in any form, the safest legal position is not to travel with a firearm at all.
Where You Park: Public Lands and Campgrounds
Who manages the land under your rig matters as much as how you transport the gun.
National Parks and National Forests
Since February 2010, federal law has allowed firearm possession in national parks and national wildlife refuges, as long as you comply with the laws of the state where the park is located.5Office of the Law Revision Counsel. 54 USC 104906 – Protection of Right of Individuals to Bear Arms If you can legally carry in Wyoming, you can carry in Yellowstone.
The exception is federal buildings. Visitor centers, ranger stations, and any building owned or leased by the federal government where federal employees work are off-limits. Bringing a gun inside is a federal crime carrying up to one year in prison.6Office of the Law Revision Counsel. 18 USC 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities Secure the firearm in your RV before walking in. National forests follow the same framework.
Army Corps of Engineers Campgrounds
This one catches people. Army Corps of Engineers recreation areas, which include thousands of lakeside campgrounds, prohibit loaded firearms. Under 36 CFR § 327.13, possession of a loaded firearm at a Corps project is prohibited unless you’re a law enforcement officer, actively hunting in a permitted area, using an authorized shooting range, or have written permission from the District Commander.7eCFR. 36 CFR 327.13 – Explosives, Firearms, Other Weapons and Fireworks Camping with a loaded gun in your RV violates the rule. At a Corps campground, your firearm must be unloaded.
BLM Land
Bureau of Land Management land is generally the most permissive. You can carry and even target shoot on most BLM land, subject to state law. Discharge is prohibited at developed recreation sites unless they’re specifically designated for shooting, and seasonal fire restrictions may temporarily close areas to target shooting.8Bureau of Land Management. Recreational Shooting
Private Campgrounds
A private campground can prohibit firearms regardless of state law or your permit. Check the policy before you arrive. Showing up armed where it’s prohibited can get you removed or, in some states, charged with trespassing while armed.
How to Store and Transport for the Whole Route
Because the rules move around you, default to the strictest standard while in transit. Treat every drive as if you’re passing through the tightest state on the map.
- Unload the firearm completely. Remove the magazine and clear the chamber. This satisfies FOPA and virtually every state’s transport law.
- Lock the gun in a hard-sided case. A cable lock through the action adds a second layer. Store the case in an exterior storage bay or a rear compartment you can’t reach from the driver’s seat.
- Store ammunition separately, in its own container, ideally locked. Some states require the separation; doing it everywhere removes a variable.
- Keep only 10-round magazines accessible. Lock any higher-capacity magazines in a separate container and leave them alone until you’re certain you’re in a state that allows them.
If you tow a car, putting the locked case in the towed vehicle adds physical separation between the gun and the passenger compartment. FOPA’s standard is that the firearm not be readily accessible from where people sit, and a locked case in a towed car meets that easily.
If You Get Pulled Over
A traffic stop with a firearm in the RV raises questions that go beyond the traffic violation itself.
Duty to Inform
Some states require you to volunteer that you have a firearm during any official contact, even if the officer never asks. Texas, Ohio, Michigan, Nebraska, North Carolina, Louisiana, and several others impose this duty. In those states, staying silent can be its own offense even if the gun is otherwise legal. In states without a duty to inform, you generally aren’t required to disclose unless asked, but calmly volunteering the information early tends to make the encounter smoother.
Searches
The Supreme Court held in California v. Carney (1985) that a motor home can be searched under the automobile exception to the Fourth Amendment based on its mobility and the reduced expectation of privacy in a vehicle. An officer with probable cause can search your RV without a warrant, even parked.9Legal Information Institute. Automobile Exception Locked containers inside generally require separate probable cause to open.
You can refuse a consent search, and refusal cannot be used against you. Consent must be voluntary, and you can limit its scope or revoke it. Once probable cause exists, though, consent no longer matters. Keep the firearm stored to the strictest standard, answer questions honestly, and don’t give an officer a reason to look further.
