getting a little head
If my memory serves me correctly, Raritan has a small head fixture and a separate holding tank molded to fit around the front of the bowl and base. It''s what I have planned to replace a porta-potti with. I picked up literature on it at the Annapolis Sailboat show several years ago. Defender doesn''t show it in their catalog any longer but may be able to special order it. Check them also for macerators if Sailnet can''t provide.
