Abstract
Abstract An elongated generally rectangular panel is pivotally secured to vehicle connected roof support members transversely of the vehicle. The length of the panel is substantially equal to the width of the roof and, when in operative position, is disposed with a depending edge disposed below and forwardly of its opposite trailing edge to define an upwardly and rearwardly inclined face portion for deflecting air currents passing over the vehicle roof, upwardly and rearwardly above the forward end of a trailer towed by the vehicle.
