The vent conduit includes a vent pipe connected to the holding tank and a vent hose connected between the vent pipe and a vent opening in the roof section. The vent hose is extendable from a first length when the roof section is in a retracted position to a second longer length when the roof section is in a raised position.

Abstract: A recreational vehicle, for example, a folding camping trailer, includes a chassis having wheels and a towing hitch, a trailer body attached to the chassis, and a storage container attached to the chassis. The storage container includes a seamless body defining an internal space for storing cargo and may define one or more access openings for a plurality of access doors. The seamless body is made of a substantially rigid material, such as plastic, and may be roto-molded to form the seamless body. The seamless body may further include an engagement panel configured for a mating connection with a corresponding receiving recess defined in the trailer body.

Abstract: 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.

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.

Abstract: A folding trailer having at least one expandable bed assembly includes a trailer body having sidewalls, end walls and a guide rail attached to each of the sidewalls. The sidewalls and end walls of the trailer body define an internal space. The folding trailer further includes a first mattress frame having extension rails slidably received in the guide rails attached to the sidewalls of the trailer body. The first mattress frame is movable between a retracted position in which the first mattress frame at least partially encloses the internal space defined by the trailer body and an open position in which the first mattress frame extends outward from an end wall of the trailer body leaving an external space between a leading edge of the first mattress frame and the end wall. The leading edge of the first mattress frame includes a support member extending into the external space.

Abstract: A folding camping trailer includes a trailer body having an end wall. An expandable bed is movable between a closed position retracted within the trailer body and an opened position extended outward from the end wall. The expandable bed includes a bed support mechanism attached to an underside of the expandable bed. The bed support mechanism is configured to connect to the end wall of the trailer body or to a towing frame of the folding trailer for supporting the expandable bed in a vertical direction when the expandable bed is in the opened position.

Abstract: A folding camping trailer having a folding step with an integrated storage compartment generally includes a trailer body defining a doorway opening, a platform having a first side and a second side and a storage compartment connected to the platform. At least one of the platform and storage compartment is pivotally secured to the trailer body such that when the platform is in a first position, the platform is received in the doorway opening, and when the platform is rotated to a second position, the second side of the platform defines a step positioned adjacent the trailer body. In the first position of the platform, the first side of the platform preferably lies substantially in a plane defined by an external surface of the trailer body and the storage compartment is accessible to users of the folding trailer. In the second position of the folding trailer the storage compartment is substantially inaccessible to users of the folding trailer.

Abstract: A folding trailer which includes a slide-out room movable from a retracted position within the trailer to an extended position which adds additional living space to the inside of the trailer. The slide-out room includes a front wall, a rear wall and an exterior wall, with the floor attached therebetween and spaced above the trailer floor. A pair of lateral roller supports attached to the trailer floor along the front wall engages a roller track attached to the inside surface of the front wall. Similarly, a pair of lateral roller supports attached to the trailer floor on the other side of the slide-out room, and adjacent the rear wall, engages a roller track on an inner surface of the rear wall. A plurality of vertical roller supports attached to the trailer floor supports and contacts the lower surface of the slide-out floor.

Abstract: A folding trailer having an integral cargo platform generally includes a chassis having wheels and a towing hitch, a trailer body attached to the chassis such that a front end of the trailer body faces the towing hitch and the platform attached to the chassis between the front end of the trailer body and the towing hitch. The platform generally includes a substantially flat and substantially rigid core member and a layer of substantially abrasion and weather resistant material positioned on the core member. The platform further includes a first side and a second side and is configured to be attached to the chassis such that the second side contacts the chassis. The first side of the platform has a surface defined by the layer of abrasion and weather resistant material, with the surface shaped to limit movement of cargo received on the first side of the platform.
