Luckily, the general rule is that you do not need a special license to drive/tow an RV weighing less than 26,000 pounds or less than 40 feet. Even better, most RVs fall under that weight and length, especially RVs that you’d be potentially renting.
A Class A motorhome is the largest drivable RV. They resemble a bus and are typically 30 to 40 feet long. They are also considered top-of-the-line amongst RVs and typically feature full bathrooms, entertainment centers, and spacious living areas.
Class B motorhomes are more commonly known as van campers because these RVs are built on a van chassis with a raised roof. Class Bs are typically the smallest drivable RV but still have a bathroom, convertible bed, and basic kitchen necessities.
