RV Fire Hazards You’ll Only Notice After It’s Too Late (Unless You Read This)

Let’s be real — nobody rolls into a campsite thinking, “Hmm, what might burst into flames today?”

But RV fires happen more often than most travelers realize — and usually because of things that look totally harmless… until they aren’t.

If you’ve ever smelled that “something’s burning” whiff and hoped it was just your neighbor’s bacon, this one’s for you.

1. The “Forgotten Plug-In” Problem

Small space, big power draw — that’s a recipe for hidden heat. Electric griddles, air fryers, and even that cute little coffee maker can overload outlets faster than you can say “breaker box.”

The fix:

• Use only one high-watt appliance per outlet.

• Unplug everything before hitting the road (vibration loosens connections).

• Consider a smart surge protector with overload alerts.

2. Propane Lines That Age in Silence

Propane is a loyal travel buddy — until a brittle hose or loose fitting turns it into a fire starter.

These lines dry out, crack, or wiggle loose with road vibration, and you won’t notice until you smell that faint “rotten egg” scent… or worse, see the flicker.

The fix:

• Do a soapy water leak test every few months.

• Replace rubber hoses every 5 years or sooner if you see cracks.

• Install a propane leak detector inside your RV (they’re cheap insurance).

3. Battery Terminals and Mouse Condos

If you store your rig for the winter, chances are the local mouse family has claimed your electrical bay. They chew insulation, build nests near wires, and — you guessed it — create perfect tinder for electrical fires.

The fix:

• Disconnect and clean batteries before storage.

• Use rodent deterrent pouches or peppermint spray in wiring compartments.

• Check for frayed wires before reconnecting.

4. The Furnace Closet of Doom

RV furnaces work hard, but the area around them often becomes the “stuff stash.” Extra paper towels, blankets, or cleaning wipes near the vent can ignite in seconds if the system overheats.

The fix:

• Keep at least a foot of clearance around furnace vents.

• Vacuum out dust bunnies and pet hair every season.

• Test your CO and smoke alarms monthly (yes, really).

5. Extension Cords That Aren’t RV-Rated

That orange garage cord you grabbed from the house? Not good. Non-RV cords can overheat fast when handling 30- or 50-amp loads — especially when coiled or buried under a rug.

The fix:

• Use heavy-duty RV extension cords rated for your amp service.

• Keep cords fully uncoiled so heat can escape.

• Inspect plugs for soft, melted edges before every trip.

6. Grease Goblins in the Kitchen

Cooking inside an RV feels homey — right up until oil splatter meets an open flame or a clogged vent fan. Grease loves to build up behind the stove hood and drip onto hot surfaces.

The fix:

• Wipe down cooking areas after each use.

• Clean filters in the vent hood regularly.

• Keep a Class B:C fire extinguisher within reach (and know how to use it).

7. The “It’s Just a Candle” Mentality

Candles, incense, and oil diffusers might make your camper smell like a spa, but in a small, constantly moving box full of fabric and plastic, open flames are never worth the risk.

The fix:

• Swap for LED candles or battery-powered diffusers.

• If you must use a real flame, never leave it unattended — and don’t light it while driving (yes, people do this).

8. Dryer Lint — The Silent Killer of Tiny Laundry Days

Portable RV washers and dryers are awesome, but lint traps are often overlooked. Combine trapped lint with high heat in a cramped vent, and you’ve basically got kindling in a tube.

The fix:

• Clean lint filters after every use.

• Check outside vents for blockages.

• Every few months, detach the vent hose and clean it completely.

9. Poorly Stored Gas Cans and Generators

That spare gas can riding in the storage bay? If it’s not secured and vented properly, fumes can collect — and one spark later, boom. Same goes for generators with leaking fuel lines.

The fix:

• Store gas cans outside the RV in ventilated containers.

• Use generator mats to catch leaks.

• Never transport propane tanks inside your vehicle.

10. Outdated Detectors and Extinguishers

If your smoke detector is yellowed, or your extinguisher’s needle is in the red, they’re not decoration — they’re expired safety tools. And when seconds count, you’ll wish you’d checked.

The fix:

• Replace smoke and CO detectors every 5–7 years.

• Check extinguisher pressure monthly.

• Mount one by the door and one near the kitchen.

Most RV fire hazards aren’t dramatic — they’re quiet, sneaky, and completely preventable with a little attention.

Take one afternoon to go through this checklist, and you’ll sleep easier knowing your home-on-wheels isn’t hiding a surprise campfire of its own.

Safe travels — and stay fire-free out there.
