A camper shell is a type of cover that fits over the bed of a pickup truck. It provides protection from the elements, such as rain and snow, while also offering additional storage space. Many camper shells are designed to be aerodynamic, which can help improve fuel efficiency when driving. These shells come in various styles and materials, including fiberglass and aluminum. Some models feature windows and doors for easy access, while others may include built-in racks for carrying gear. Camper shells are popular among outdoor enthusiasts, as they allow for camping and transporting equipment without the need for a full-sized trailer.
