Abstract: A vehicle frame with a low profile is designed to be suitable for attaching directly to an incomplete, preassembled motorized chassis to construct a motorhome. The vehicle frame includes planar bulkheads and a storage area floor that are attached to the frame and to the chassis so as to create a three-dimensional space frame that is highly resistant to bending and twisting forces as well as storage areas that extend the width of the motorhome. The motorhome with the frame mounts a heating, ventilation, and air conditioning (HVAC) system as well as heavy holding tanks within or below the plane of the vehicle frame so as to lower the center of mass of the motorhome to thereby improve vehicle handling and safety. Placement of the HVAC system within and/or below the vehicle frame obviates the need to position HVAC components on the roof of the motorhome thereby further lowering the center of mass and eliminating a source of liquid water condensation above the living space of the motorhome.

Abstract: A recreational vehicle having an extendable slide-out controlled by an actuator assembly is provided with a damage avoidance system. The damage avoidance system determines if the slide-out is in an adverse state and, if the adverse state is detected, inhibits the actuator assembly from moving the slide-out. The slide-out is in the adverse state if (a) a collision between the slide-out and a nearby object is imminent, (b) a collision has recently occurred, or (c) a resistive force is acting on the slide-out which substantially inhibits the actuator assembly from moving the slide-out. The damage avoidance system comprises a sensor module for monitoring the state of the slide-out and for providing an override signal to the actuator assembly, wherein the override signal is indicative of the slide-out being in the adverse state.

Abstract: A recreational travel trailer comprising a main housing which encloses a living space having multiple floor levels, and a two level extendable housing having a deployed configuration and an extended configuration. The extendable housing is movably positioned within an opening in the main housing so that a first floor of the extendable housing is positioned adjacent to a first floor of the main housing and so that a second floor of the extendable housing is positioned adjacent to a second floor of the main housing. In the deployed configuration, the extendable housing extends through the opening of the main housing so as to increase the enclosed space within the trailer. In the retracted configuration, the extendable housing is substantially positioned within the main housing so as to provide the main housing with a shape and size that is suitable for being towed on a public road. The trailer is further comprised of a two level actuator assembly which moves the two level extendable housing.

Abstract: A fifth wheel travel trailer having an improved chassis, the chassis comprising a rear section, a mid-section, and a front section disposed in vertically offset horizontal planes. The trailer further comprises a carriage member having a plurality of rotatable wheels mounted underneath the rear section of the chassis and a housing member having an interior living space formed therein mounted above the chassis. The rear section of the chassis comprises a pair of main longitudinal members each having a pair of stacked I-beams such that upper surfaces of the main longitudinal members define a first horizontal mounting plane suitably elevated above the wheels of the carriage assembly so as to enable a rear section of a floor assembly to mount directly to the rear section of the chassis in the first mounting plane to thereby increase the rigidity of the rear section of the chassis.

Abstract: A recreational vehicle having an expandable room wherein the room can be positioned in a retracted or deployed configuration. In the deployed configuration, the room expands inwardly into the main housing of the vehicle so as to enlarge the area of the room without displacing the fixtures and plumbing that are typically positioned adjacent an outer wall of the room. The room can be extended in conjunction with an exterior slide-out assembly wherein the deployed slide-out assembly creates a larger inner living space so as to accommodate the expanded room.

Abstract: Disclosed is an awning assembly for a recreational vehicle. The awning assembly includes an awning that is configured to be extended from a sidewall of the recreational vehicle to provide shade. A rug is removably mounted to one edge of the awning. In use, the rug is removed from the awning and positioned on the ground below the awning to serve as a ground covering. When not being used, the rug is attached to the awning and stored with the awning in an awning housing to save space. In another embodiment, the awning assembly comprises a rug housing that is configured to be moved between a storage configuration and an extended configuration.
