My wilcox critten marine toilet can be a real pain to use,I do OK but I have almost always check it after other guest.So I know this has been discussed many times but I am really askingsome one who has done this change over from my similar manual toiletto the raritan sea era electric fresh water or the same toilet in raw water.How was the change over and installing of this unit,does it fit and what ifany problems with the base not so much about the water hook up or the electric hook up. I am really interested with the toilet itself fitting in base bolted down,I don'tsee a problem me running water or electric,just it the tiolet fitting in OK.Nick
