Abstract: A slide-out room and awning assembly for a recreational vehicle. The assembly includes a roll enclosure for attachment to an exterior side wall of the vehicle, a roll rotationally journalled within the roll enclosure, a slide-out room for extension from the exterior side wall, an elongated trough attached to the slide-out room, and an awning fabric attached at a proximate edge to the roll and attached at a distal edge to the elongated trough. When the slide-out room is in a retracted position, the awning fabric is wrapped around the roll. When the slide-out room is in an extended position, the awning fabric is extended from the roll over a top wall of the slide-out room at a downward slope from the roll to the trough such that debris and liquid flow into the trough.
