The ramp is pivotable relative to the frame assembly and has a deployed position and a stowed position. The drive member is configured to move the ramp between the deployed position and the stowed position. The counterbalance mechanism includes a gas strut having a first end and a second end. The first end of the gas strut is secured to the frame assembly and the second end of the gas strut is movable relative to the frame assembly. The first and second engagements of the drive member are configured to engage the second end of the gas strut.
