Which of the following is a characteristic of a towable recreational vehicle?

A towable recreational vehicle is a type of RV designed to be towed by another vehicle rather than being driven itself. The defining characteristic of option B highlights that these vehicles are built on a chassis and often come equipped with amenities that support living, such as kitchen facilities, sleeping areas, and bathroom facilities, which can be seen as life-support systems for camping and recreational use. This aligns with the general understanding of what constitutes a recreational vehicle.

In contrast, the other options present characteristics that do not accurately describe towable recreational vehicles. For example, the idea that a towable recreational vehicle must always have a motor is incorrect, as their nature is to rely on being towed by another vehicle. The statement about being solely for transporting property is also misleading since these vehicles are intended for recreation and personal use, not just for cargo transport. Lastly, while some towable RVs can be large, there is no strict size limitation of exceeding 26 feet to classify it as a towable recreational vehicle; they can come in various sizes, depending on the model and design. Thus, the correct answer emphasizes the built-in features that define a towable recreational vehicle.
