Abstract
Abstract A portable shelter having a storage container and a roof and wall section that folds in 180* folded configuration for storage in the storage container, leaving a large storage space in the lower portion of the container. Foldable roof support beams are stored below the roof and wall section in the container. End walls are hinged to floor sections which fold out from opposite sides of the storage container. Flysheets are secured to the roof and wall sections and have locking seals which attach to flanges on the central container endwalls and floor to provide seals. Leveling jacks are attached to the floor sections to level the floor of the shelter.
