An operable ramp is moveable between a stowed position and a deployed position. The operable ramp includes a ramp panel rotatable about a first end. A second end of the ramp panel is lower in the deployed position than in the stowed position. A rotatable support supports a second end of the ramp panel, and a drive assembly selectively rotates the support (1) in a first direction to lower the second end of the ramp panel and (2) in a second direction to raise the second end of the ramp panel. A stop limits rotation of the support in the second direction when the operable ramp is in the stowed position. The weight of the ramp panel biases the support in the second direction, i.e., toward the stop, when the operable ramp is in the stowed position.
