Abstract: An apparatus includes a housing which is mounted on the lower portion of the inside of a rear window of a vehicle. The housing extends across the width of the rear window. A pair of support arms are pivotally mounted, one each, on the sides of the housing. During storage, the support arms are generally parallel to and are attached to the front wall of the housing by a clip. The support arms can swing outwardly to provide support for an awning which is rolled onto a roller inside the housing. During use, when the rear window has been opened, the support arms are swung in an outward direction. The awning is which is pulled outwardly and the end of the awning is hooked onto the outer ends of the support arms. The awning, which is made of a waterproof material, includes a support member which extends between the outer ends of the support arms. When the awning is rolled back into the housing, the housing catches and collects moisture from the awning and prevents water damage to merchandise stored in the vehicle.
