A travel trailer is a popular type of RV that can be towed behind a car or truck. Travel trailers come in various sizes and styles, and they're an excellent option for campers who want to enjoy the flexibility of being able to pack up and go whenever they want. A recreational vehicle (RV) is a motor vehicle or trailer with living quarters. Motorhomes, caravans, pop-up campers, truck campers, and fifth-wheel trailers are all examples of RVs.
