A camper having passive solar climate controls. The camper has a solar structure carried by a base. The solar structure includes a cover, a window panel, a ridge vent, a plurality of awnings, and a plurality of side panels. The ridge vent and the awnings are carried by the cover and the window panel. The window panel and the cover are each pivotally attached to the base such that they are rotated toward the base into a collapsed position and/or away from the base into an extended position. A gable connector secures the cover and the window panel in the extended position. The side panels cooperate with the cover and the window panel to define an interior within the camper.
