According to the Insurance Information Institute’s table of Automobile Financial Responsibility Laws by State, 49 out of all 50 states, as well as the District of Columbia, require you to have some sort of liability coverage for all vehicles on the road, including RVs. The only exception to this rule is the state of New Hampshire, which has no mandatory insurance law, and only requires financial responsibility from the person at fault in a car accident.
Most car insurance providers will offer to include your RV as part of your auto insurance policy, as such you will get traditional car insurance coverage. This will include bodily injury and property damage liability coverage, personal injury protection, collision, comprehensive, medical payments, and uninsured or underinsured motorist coverage, which essentially protects you against accidents and physical damage while on the road. (For a more detailed explanation of coverage see below.)

When judging coverage and benefits, we singled out RV insurance carriers that offered extensive and flexible coverage options. To be considered for our list, companies had to provide all the traditional insurance protection, as well as a healthy amount of RV-specific options. Most RV insurers offer liability, personal injury protection (PIP), collision, underinsured or uninsured motorist, and comprehensive coverage. Other types, such as full-timer and Mexico coverage, vary in availability from company to company.
