Class A RV’s are the largest motorhomes available, defined by their boxy shape and a large framework, as they are often built on a truck or bus chassis. Some of these recreational vehicles are 45 feet long and can use up a gallon of oil in just 8 to 10 miles. Class A RV’s are the preferred option for people living in motorhomes full-time, but they do incur an above-average RV insurance cost.
Class C RV’s are visibly smaller, and are usually built on a van or truck chassis. This vehicle has a cab attached to it, as well as an overhand that extends over the cab and is usually used as a sleeping area. They are also much more economical, as you can drive 10 to 15 miles per gallon.
