RV Insurance companies take these type of risk factors into account, which makes it more difficult for bus-conversion homeowners to find the best coverage. Also, buses first need to be registered as RVs with the department of motor vehicles beforehand. If not, they’re still considered commercial vehicles instead of personal, and will not qualify for RV insurance. Different states have different requirements as to what qualifies as an RV, many of which include repainting the bus a different color, having a potable water supply, installing a toilet, and having cooking appliances onboard.
Still, regardless of whether your state requires you to have an RV insurance policy, it’s always best to have one if you plan on living in your RV full-time to protect yourself and your vehicle against any damages and covered losses. On the other hand, if you plan on using your RV seasonally or for short trips, then liability coverage might be enough.
