In yet another aspect of the invention, a heat exchanger for cooling engine coolant may be provided at the rear of the tunnel. The heat exchanger may be mounted to and partially spaced from the molded rear member. The heat exchanger may bear rearwardly extending ridges with upwardly extending lip at the far end. In some embodiments, a channel is provided on the upper end of the heat exchanger to promote air and snow flow over the rearwardly extending ridges.
