Expandable travel trailer

A travel trailer, comprising:

• a chassis having wheels;
• a trailer body attached to the chassis and comprising rigid sidewalls, a rigid front end wall, a rigid rear end wall, a rigid roof, and a floor, the sidewalls, end walls, roof, and floor defining an internal space of the trailer body;
• and
• a slide-out area extendable outward from the trailer body, the slide-out area 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 comprising:
• a rigid roof;
• rigid sidewalls connected to the roof;
• a rigid bottom wall connected to the sidewalls;
• and
• a rigid front end wall connected to the roof, sidewalls, and bottom wall,
• wherein the slide-out area is extendable from one of the sidewalls of the trailer body, the one sidewall of the trailer body defining at least one opening for receiving the slide-out area into the trailer body, and the front end wall of the slide-out area adapted to seal against the trailer body in the retracted position.

A sealing arrangement for a travel trailer comprising a trailer body with a slide-out area, the trailer body defining an opening for receiving the slide-out area into the trailer body, and the slide-out area movable between a retracted position received substantially within the trailer body and an extended position extending outward from the trailer body, the sealing arrangement comprising:

• a first flange plate connected to the trailer body and extending into the opening in the trailer body accommodating the slide-out area, the first flange plate having a pair of sealing gaskets attached to opposite sides thereof;
• and
• a second flange plate attached to an end of the slide-out area received within the trailer body,
• wherein when the slide-out area is in the extended position the second flange plate engages one of the sealing gaskets attached to the first flange plate to provide a substantially weather tight seal between the slide-out area and trailer body, and wherein when the slide-out area is in the retracted position a front end wall of the slide-out area engages the other of the pair of sealing gaskets to provide a substantially weather tight seal between the slide-out area and trailer body.
