The three types of motor homes are Class A, Class B, and Class C. Before venturing to rent a motor home, you should be clear about what you want. Class A is definitely roomier and larger than the others, while Class C is usually held to be the safest, with air bags and seat belts. Research shows that Class C motor homes are popular because of their safety level, which is the highest safety in auto accidents among all motor homes. Apart from this, they also have more sleeping capacity and better fuel consumption as well.Designed for local roads and other conditions, motor homes are available in sizes ranging from 22 feet to 32 feet and even more.
