Abstract

The travel trailer includes a chassis having wheels and a trailer hitch for towing the travel trailer. The travel trailer further includes a trailer body attached to the chassis defined by sidewalls, a front end wall, a rear end wall, a roof, and a floor. The sidewalls, end walls, roof, and floor form an internal space of the trailer body. A slide-out area is slidably extendable outward from the trailer body. The slide-out area is extendable from a retracted position received within the trailer body to an extended position extended outward from the trailer body. The slide-out area includes a peaked roof, sidewalls, a bottom wall, and a front end wall. The front end wall includes a flange extending around the perimeter thereof. A sealing gasket is attached to the flange to face the trailer body for sealing against the trailer body in the retracted position of the slide-out area.
