Does car insurance cover a travel trailer?
Only partly. Your car insurance's liability coverage usually extends to a travel trailer while it is hitched to your insured vehicle, so damage the trailer causes to others on the road is generally covered. It does not pay for damage to the trailer itself, its contents, or liability once the trailer is unhitched and parked. For that you need a separate travel trailer policy with comprehensive, collision and, ideally, vacation liability. California's specific rules are in our California RV insurance guide.
- Liability usually follows the tow vehicle: covered while hitched, generally not once unhitched.
- Damage to the trailer itself is never covered by your auto liability.
- Contents inside the trailer may have limited coverage under a homeowners policy, but often not enough.
- Lenders require comprehensive and collision on a financed trailer.
- California does not require separate insurance on a towable trailer; motorhomes do need 30/60/15.
What Your Auto Policy Does and Doesn't Do
• Not covered: Damage to the trailer from a crash, rollover, fire, theft, hail or a falling branch.
• Not covered: Liability when the trailer is parked and unhitched at a campsite.
• Not covered: Your belongings inside, beyond whatever off-premises limit your homeowners or renters policy provides.
Check your policy wording; some insurers add trailer endorsements. Our guide on how to read an insurance policy shows where trailer language usually appears.
What a Travel Trailer Policy Adds
A loaded trailer adds weight and stopping distance. If you carry only state minimums, a towing crash can exceed them quickly. California's floor is 30/60/15; see California evidence of liability insurance.
Do You Legally Need Trailer Insurance?
Illustrative Case: The Campground Storm
Scenario: An illustrative owner unhitched a travel trailer at a state campground. Overnight, a storm dropped a branch through the roof, causing an estimated $7,800 in damage. The owner had only auto liability on the tow vehicle.
Resolution & Judicial Outcome: The auto insurer declined: liability covers damage to others, not the owner's trailer, and the trailer wasn't hitched. The owner paid out of pocket. A trailer policy with comprehensive coverage would have paid the repair minus the deductible.
What You Should Do: Step-by-Step Action Plan
Critical Mistakes to Avoid
- Assuming 'full coverage' on the truck extends to the trailer's own damage.
- Leaving the trailer uninsured in storage, where fire and theft risks continue.
- Insuring a new trailer at actual cash value and losing thousands to depreciation.
- Towing with state-minimum liability limits.
