Abstract: A method of making a RV and a RV made thereby having a plurality of compartments whose floorspace ratio can be selectively altered according to the usage status of the vehicle without increasing the total floorspace footprint by internal movement of structural features and user fixtures normally supported on the vehicle floorspace. For example, an RV can be made wherein the relative position of a dividing wall between compartments is movable with respect to those compartments and, at the same time, a seating fixture within one compartment can be moved along the floor between optimizable positions according to the usable floor space within that compartment.
