An RV, or recreational vehicle, is a motor vehicle or trailer that includes living quarters designed for accommodation. RVs can either be trailers (which are towed behind motor vehicles) or self-propelled vehicles. There are many different types of RVs, including:

• Motorhomes: These are self-propelled vehicles that include living quarters and a cab for the driver and passengers. Motorhomes are categorized according to their class — Class A, B, or C.

• Travel trailers: These are towable RVs that range in length from 13 to 35 feet and are attached to the rear frame of a towing vehicle using a tow hitch.

• Fifth wheels: These are towable RVs that attach to a special hitch in the bed of a pickup truck.

• Pop-up trailers: These are lightweight and compact towable RVs that fold up for easy towing and storage. They are also known as folding trailers.

• Toy haulers: These are RVs that have a living space in the front and a garage in the back for hauling dirt bikes, golf carts, and other toys.

RVs are designed to provide accommodations while traveling, and people often use them for road trips or camping. The exact definition of an RV varies from state to state, so its important to check with your local DMV before making a purchase.
