The rear support frame includes a plurality of first support members extending therefrom, and the aft edge portion of the deck includes a plurality of second support members pivotally coupled to the first support members along an axis. The seal of this embodiment includes a first edge portion extending outwardly from a medial portion in a first direction, and a second edge portion extending outwardly from the medial portion in a second direction. The medial portion urges the first edge portion against the support frame and the second edge portion against the aft edge portion of the deck as the deck pivots about the axis in operation.
