In various embodiments of the present disclosure, a cargo bed pivoting panel assembly is provided. The assembly includes a panel having a pair of studs extending from corresponding opposing ends of the panel adjacent a bottom of the panel. The assembly additionally includes a main body having a first deck portion and a pair of opposing sidewalls extending substantially perpendicular from the first deck portion. Each sidewall includes an elongated receptacle for receiving, and slideably and pivotally retaining, a respective one of the studs. Accordingly, the panel can be moved between a stowed position and a deployed position by sliding the studs between first ends of the elongated receptacles and second ends of the elongated receptacles while simultaneously rotating the panel about a centerline of studs.
