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

A key component of a folding camper's functionality is the collapsible sides. This design allows the camper to expand and contract, making it portable and easy to store. When not in use, the camper can be folded down to a compact size, which is essential for ease of transport and storage. The ability to quickly set up and take down the camper is a significant advantage for users who may want to set up their campsite without extensive labor.

The collapsible design also contributes to the camper's overall weight and aerodynamics, improving fuel efficiency while towing. Therefore, this feature is integral to the camper's practical use, providing both convenience and functionality for outdoor enthusiasts.
