Abstract: A transformable cover assembly for pickup trucks is user switchable between a low profile, bed cover configuration and a fully deployed, camper configuration. The apparatus unfolds from a planar orientation into a pair of cooperating, stacked, generally wedge-shaped segments. The segments are complementary; the stacked wedge-shaped segments form an inhabitable enclosure in the general form of a parallelepiped when erected. A planar deck that is foldably deployed comprises a top that ultimately covers the upper segment, and a shroud that unfolds to form a border between the adjacent, deployed segments. A foldable framework comprising a plurality of cooperating members enables foldable transformation. As the assembly deploys it unfurls pliable, generally triangular walls at the segment sides.
