Abstract: For use as an accessory with a multi-purpose vehicle having enclosed and rooftop cargo storage, a ladder/ramp includes a pair of siderails and crossbars extending between the siderails. A plurality of panels are each rotatably mounted between the siderails adjacent to one of a plurality of the crossbars, with each panel selectively rotatable between a closed position substantially aligned with the siderails and an open position extending outwardly from the siderails. When the panels are in the closed position, the panels and the crossbars collectively form a substantially continuous surface between the siderails on which wheels can be rolled. When the panels are in the open position, the panels each form a step that may support at least about 250 pounds. The panels may snap into place when moved into the open or closed positions, to prevent inadvertent movement therefrom.
