Wheeled assembly for item transport

A shipping assembly comprising:

• a rectilinear shipping module of interrelated and pivotally connected wall, floor and ceiling components of a structure for occupancy, the shipping module having a lower first transverse edge, a lower second transverse edge and a length;
• a first transport assembly and a second transport assembly, each transport assembly comprising a chassis;
• two opposed wheels pivotally mounted on the chassis to permit the transport assembly to be steered;
• means for fixing the angular orientation of the two opposed wheels at a select one of multiple angular orientations, so as to be able to vary the turning radius of the shipping assembly;
• a support assembly secured to the chassis and adapted to be positioned in a mating relationship with the shipping module proximate to a lower transverse edge of the shipping module;
• means for removably securing the support assembly to the shipping module;
• and a displacement actuator secured between the chassis and the support assembly, said displacement actuator for varying the ground clearance of the shipping module when secured to the support assembly;
• the first transport assembly removably secured in a mating relationship with the shipping module proximate to the lower first transverse edge thereof, and the second transport assembly removably secured in a mating relationship with the shipping module proximate to the lower second transverse edge thereof;
• and
• a towing element secured to the chassis of the first transport assembly.
