Claim:
A sanitary system for a motor vehicle, the system comprising: a bowl assembly; a toilet base supporting the bowl assembly, the bowl assembly coupled to the toilet base; a mobile holding tank removably coupled to the bowl assembly for receiving waste from the bowl assembly and stowable within a storage area defined by the toilet base, the mobile holding tank including a top surface enclosing the mobile holding tank upon removal from the bowl assembly; and a pumping arrangement including a first portion carried by the toilet base and a cooperating second portion carried by the mobile holding tank, the first and second portions having cooperating structure for interconnecting together to define a fluid path from the mobile holding tank to a remote waste storage for the pumping of waste from the mobile holding tank; wherein movement of the mobile holding tank into the storage area both automatically couples the mobile holding tank to the bowl assembly and automatically slidably engages the first portion with the second portion so as to define the fluid path from the mobile holding tank to a remote waste storage tank, and further wherein movement of the mobile holding tank out of the storage area both automatically decouples the mobile holding tank from the bowl assembly and decouples and the first portion from the second portion.
