Abstract: An extended cab truck storage seat is disclosed. The storage seat comprises a box of an essentially rigid material with a front wall and a rear wall and parallel side walls coupled at their side edges to the side edges of the front and rear walls. The box includes a lower wall coupled at its front, rear and side edges to the bottom edges of the front, rear and side walls. The front and rear walls have a recess extending upwardly from their lower edges about an essentially common axis of rotation. The lower wall has an intermediate extent coupled at the front and rear edges thereof to the peripheral edges of the recesses of the front and rear walls. The front, rear, side and bottom walls are fabricated of steel and define an open rectangular top at the top edges of the front, rear and side walls. A lid has peripheral front, rear and side edges adapted to overlie the upper edges of the front, rear and side walls of the box.
