By law, any type of registered vehicle must be insured. Motorhomes, like cars, are required to at least have liability insurance. Travel trailers and other towable RVs, on the other hand, cannot be driven and therefore aren’t required to have insurance. Keep in mind that towable RVs, although not vehicles, are still susceptible to theft, damage from natural disasters, vandalism, and collision, so it is highly recommended for them to still have coverage.
Car insurance rates vary greatly depending on age. Your risk profile as a driver will change throughout your life, so you may be eligible for discounts at some points in your life while other times you may see your car insurance premium increase. This is why you want to keep shopping for car insurance throughout your life so you ensure the best value.
