Welcome to our group. Many of us have coaches of your era. They came with a simple mechanical toilet which gravity feeds into the tank below . Sadly, this is an area that i have some hands on experience in. Ours came with a Dometic 320 toilet, but all of the 300 series Dometics will fit. Every Newell is different, but this is one area that we seem to have in common, unless a previous owner has done modification.
