Abstract: A retractable awning for recreational vehicle slide-outs prevents rain, snow and other debris from collecting on the roof of the slide-out. The awning is provided with an inner edge secured to the adjacent wall of the recreational vehicle immediately above the slide-out roof. The opposite edge of the awning is connected to a roller journaled on arms pivotally mounted on the outer face of the slide-out. The arms provide oppositely extending lateral projections so that they can support a roller having a length greater than the spacing between the arms. Since the roller must be wider than the awning, the roller has a length exceeding the width of the slide-out roof, and the awning has a width at least equal to the width of the slide-out roof so that full coverage of the slide-out roof is provided. The roller support arms can be pivoted down to provide a typical awning for a window provided in the slide-out.
