What's the difference between a camper and an RV?

The main difference between a camper and an RV is that a camper cannot be driven independently, while an RV has its own motor. According to the RV Industry Association, an RV is a vehicular unit designed for temporary living quarters, either with its own motor or towed by another vehicle. Campers are generally smaller and less expensive than RVs, but may have fewer amenities. RVs come in three classes (A, B, C) based on size and chassis, while campers include fifth-wheel trailers and conventional travel trailers.
