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.
1 If your RV is totaled or stolen (and not recovered) in its first five model years it will be replaced with a comparable new RV, even if you’re not the original owner. After the first five model years, you will receive your full original purchase price — not a depreciated amount — toward the purchase of the replacement RV. Replacement Cost Coverage must be purchased during the RV’s model year or within the following four years.
Choosing the lowest price/inadequate coverage. The lowest prices will typically leave you vulnerable on the back end; should an accident or collision occur, your lower premium will require you to spend much more out of pocket. The same goes for inadequate coverage. Specifically, don’t cut corners when it comes to liability coverage; instead, shop around for the provider that will protect you most while also catering to your needs, lifestyle, and budget.
