Claim:
A motorhome comprising an integrated shell, the integrated shell comprising two superposed chasses: An upper chassis comprising a floor spanning a length of the motorhome; A lower chassis comprising three portions: (a) a rear portion which supports an engine-transmission assembly and a tandem axle; (b) a front portion which receives a steering axle and a driving cab; (c) a central portion which houses an elevator, and an elevator mechanism, and a mechanical system adapted to load and unload a car, said system being comprised of an assembly of three superposed elements: (i) a lower element comprising a pivoting frame, the pivoting frame comprising two or more ends, wherein one end comprises two vertical toothed racks in semi-circle, and another end comprising two half shafts and a vertical shaft rotating in a central bore of the low chassis, wherein a rotation of the pivoting frame is effectuated by a roller chain traveling on a toothed wheel freely rotating on an axle fixed on the frame and connecting two toothed wheels, one that is stationary affixed to the chassis of the motorhome and another wheel at the end of a shaft of a gear motor comprising a vertical axle affixed to the frame; (ii) an intermediate element comprising an inclinable structure, wherein one end of the structure is articulated around two half shafts of the lower element; and wherein the other end of the structure rises and falls by means of gear motor having a horizontal axle affixed to the structure, wherein the gear motor is driven by means of a chain, a shaft comprising two pinions at ends of the shaft which pinions are geared on the two toothed racks of the lower element; and (iii) an upper element comprising a platform supporting the car, sliding on the inclinable structure by means of two slides and affixed to one of the chain links of a roller chain connecting a free toothed wheel whose axle is fixed on an upper portion of the inclinable structure to a toothed wheel mounted at an end of a shaft of a gear motor having a vertical axle fixed also to the upper portion of the inclinable structure.
