There is no definitive answer to this question as it depends on a number of factors, including the type and value of your RV, your driving history, where you plan to travel and how often you plan to use your RV. However, there are some general things you can expect when insuring an RV for full-time living.
RV insurance typically costs more than auto insurance because RVs are considered both a vehicle and a home. This means that your policy will likely include coverage for both personal liability and property damage, as well as for any contents inside your RV (like furniture, electronics, etc.). You may also be required to carry additional coverage if you have a loan or lease on your RV.
The best way to get an accurate estimate of what your insurance will cost is to contact a few different companies and request quotes based on your specific circumstances. Be sure to ask about any discounts or special programs that might be available (such as those for safe drivers or frequent travelers).
