Abstract: Techniques are disclosed relating to a loading ramp. In one embodiment, the ramp includes a hitch mount that includes a horizontal portion configured to detachably couple to a tow hitch and a vertical portion extending upwards from the horizontal portion. In this embodiment, the ramp includes first and second coupled ramp members configurable as a ramp in an open position. In this embodiment, the first ramp member is rotatably coupled to the vertical portion of the hitch mount. In the open position, the ramp members may define a ramp surface usable to load light vehicles or cargo, for example, into a truck bed. In this embodiment, the first and second ramp members are configurable in a closed overlapping position in which the first and second ramp members are substantially parallel to the horizontal portion of the hitch mount.
