"The term recreational vehicle (RV) is often used as a broad category of motor vehicles and trailers which include living quarters designed for temporary accommodation. Types of RVs include motorhomes, campervans, caravans (also known as travel trailers and camper trailers), fifth-wheel trailers, popup campers, and truck campers."
All the above categories of RV can qualify for Boondockers Welcome guest privileges - but only if the RV is also self-contained.
However, NO tents, mini-vans, cars, or pick-up trucks will be allowed to join as guests. Even if your mini-can or car is fully self-contained, they are not allowed in the program.
