The travel trailer includes a chassis having wheels and a trailer body attached to the chassis. The trailer body includes sidewalls, a front end wall, a rear end wall, a roof, and a floor. The sidewalls, end walls, roof, and floor form an internal living 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 substantially within the trailer body to an extended position extended outward from the trailer body. The slide-out area has a roof, sidewalls, a bottom wall, and a front end wall. The front end wall of the slide-out areas is adapted to seal against the trailer body in the retracted position.
