A device aerodynamically designed to lessen air drag in trailers, commonly referred to as a wind deflector, and specifically related recreational trailers having a window at the front end, the device being manually shiftable to a second position, wherein it is self-supporting, to function as an awning for the front window. When functioning as a drag reducer or wind deflector the device is a simple horizontal wedge extending across the major width of the trailer except that the upper and lower panels of such wedge are isosceles trapezoids, and generally triangular wings are provided at each end of the wedge to provide a carefully limited bilateral deflection of the air for minimizing turbulence and streaking of the sides of the trailer during use.
