A shelter or camper that provides improved portability and protection. The shelter or camper may include rigid walls to offer greater protection from weather, animals, and theft. The shelter or camper may be transitionable between different configurations for different purposes, including an open and expanded configuration for use as a shelter, camper, or sleeping quarters and a compact, closed case configuration for easy storage and transport. To facilitate this, the walls may be foldable, expandable, or collapsible. When the walls are folded or collapsed, roof and floor sections may be connected to each other and may enclose the folded, collapsed walls and internal components within the collapsed closed case.
