What is a key component of a folding camper's functionality?

The key component of a folding camper's functionality is its collapsible sides. This feature enables the camper to be compacted and stored easily when not in use, facilitating transportation and reducing the space needed for storage. The collapsible sides are essential for the design of folding campers, allowing them to expand when set up for camping and retract when it's time to go home. This functionality is central to the concept of a folding camper, making it versatile for users who require mobility and limited storage space.

Other features, such as a self-leveling system, sliding mechanisms, or detachable roofs, may be found in various camping trailers, but they do not define the fundamental purpose and design of folding campers as effectively as collapsible sides do. The collapsible nature is crucial for the convenience and practicality that folding campers offer, allowing them to retain a low-profile design when closed and provide a larger living space when expanded.
