What purpose do camper shells serve?

Camper shells provide covers for the cargo beds of pickup trucks, allowing the beds to serve as sleeping areas and protecting cargo or passengers from the elements. Some camper shells also improve the aerodynamic characteristics of vehicles.

Camper shells are popular with hunters, fisherman and other outdoor enthusiasts who require a place to stay overnight in the wilderness but do not or cannot utilize full-size motor homes for their trips. Some camper shells can be removed and reattached from a vehicle easily, allowing truck owners the flexibility of having a camping vehicle and an open pickup as their situation requires.
