Hi Rodney, it's my understanding that R22s came in both versions that have a traditional marine head and those that have a porta-potty (sometimes called a cassette toilet).  Mine is the kind with the cassette toilet, which I assume came from the factory that way.  I think mine is a Dometic brand which is used for campervans in addition to boats.  I did add some tie downs to keep it extra secure since it can be top heavy when it is filled with clean water to flush with and the bottom portion is still empty - I guess you could call that "fresh" mode.  I did end up adding another shelf (above the existing shelf that came from the factory) in order to take advantage of some of the space.  The bulkhead and floor is the way it came from the factory, though I've mounted a number of things on both sides of the bulkhead. I hope that provides some context.  There are a lot of R22 owners on this list with a lot more knowledge and history than I have, so if you have more specific questions about the different head options they could probably provide more detail.
