The method of claim 9, further comprising supporting the toilet bowl assembly on the side wall by a respective bottom of each of the downwardly extending members contacting a surface of the side wall when the toilet bowl assembly is removably secured to the base assembly. 11. The method of claim 9, wherein: the base assembly comprises a plurality of said side walls, each having a respective said vertically extending wall extending from a respective top surface of the respective side wall, the vertically extending wall having a plurality of the horizontally extending members extending therefrom, the horizontally extending members being positioned such that said respective spaces are formed between the horizontally extending members; andthe receiving step comprises receiving a respective one of the horizontally extending members extending from each of the vertically extending walls into a respective said gap to thus removably secure the toilet bowl assembly to the base assembly. 12. The method of claim 9, further comprising: using a tool to couple a fastening member to the base assembly and the toilet bowl assembly to further secure the toilet bowl assembly to the base assembly. 13. The method of claim 9, further comprising: mounting the base assembly on a mounting member that is secured to a vehicle, the mounting comprising:placing the base assembly at an angle with respect to the mounting member such that a horizontally extending mounting extension of the base assembly is received by a horizontally-oriented recess of a mounting portion of the mounting member; androtating the base assembly to move a downward projection of the base assembly into a mating position with a respective vertically-oriented recess in the mounting portion. 14.
