Abstract:
A fifth wheel travel trailer comprising:a floor assembly comprising a main section and at least one elevated section; a carriage assembly comprising a plurality of rotatably mounted wheels so as to provide the trailer with mobility; a chassis having a main section and at least one elevated section, wherein the main section of the chassis comprises a first and a second longitudinally extending main longitudinal member each having an upper and a lower mounting surface separated by a first height, a plurality of longitudinally extending inner longitudinal members each having an upper and a lower mounting surface, and a plurality of laterally extending inner cross members each having an upper mounting surface, wherein the plurality of inner cross members are laterally disposed between the main longitudinal members so as to interconnect the main longitudinal members such that the upper mounting surfaces of the main longitudinal members align with a first mounting plane and such that the upper mounting surfaces of the inner cross members align with a second mounting plane positioned beneath the first mounting plane, wherein the plurality of inner longitudinal members are disposed between the main longitudinal members such that the lower mounting surfaces of the inner longitudinal members are positioned adjacent the upper mounting surfaces of the inner cross members and such that the upper mounting surfaces of the inner longitudinal members are substantially aligned with the first mounting plane, wherein the main longitudinal members and the plurality of inner longitudinal members provide rigidity along the longitudinal direction and the plurality of inner cross members provide rigidity along the lateral direction, wherein the first height of the main longitudinal members is selected so as to permit direct mounting of the floor assembly on the first mounting plane and direct mounting of the carriage assembly to the lower mounting surfaces of the main longitudinal members, wherein the floor assembly mounted directly on the first mounting plane further rigidifies the main section of the chassis, wherein the space between main section of the floor assembly, the main longitudinal members, the inner longitudinal members, and the inner cross members defines a plurality of longitudinally extending channels; and a housing member comprising a plurality of walls so as to define an interior living space therein, wherein the housing member upwardly extends from the chassis so as to receive support therefrom.
