What Does RV Mean?

RV stands for recreational vehicle, which includes vehicles that have motors and those without. Recreational vehicles, also known as RVs, are vehicles or trailers that include accommodation-focused amenities such as living space, sleeping arrangements, cooking setups, and more.

RV is the term used to refer to these vehicles which are often used for vacations, full-time living, and everything in between. For a vehicle to meet the RV definition, it needs to include a designated space for living such as a sleeping area or living room. A vehicle may be an RV if it just has a bed, or it may be an RV with a more complex setup like a residential kitchen. RVs are available in many sizes and can include a wide variety of features.
