Yes, interiors vary wildly on SJ's, but your much later year must be a Catalina made Morgan-45? Or is that Nelson-Merrick? Love to see pics! I saw a YouTube video of someone's Catalina Morgan-45 that was for sale and it was a gloriously plush and roomy inside yacht!
Sure both the AirHead and Natures Head are completely self contained. One of the advantages is that you can close up at least one thru-hul.

C-Head seems to be a more inexpensive option. It does not look quite as compact as the others, but it is about half price. It also looks a bit more "thrown together" but appears functional.

You can build one yourself too, but I have never seen one that looks really nice, or as easy to operate.
