Replacing Aqua Magic IV with Dometic 310 Question

You might want to do a Google search on the Dometic 310. It has a history of leaks between the porcelain bowl and plastic base. You cannot fix it per Dometic. I had one in a 2012 and it leaked from the start. Dealer worked on it twice and finally I just replaced it with a Thetford AM Plus unit. This is also a porcelain unit. The factory replaced the Dometic 310 which is stored in my outbuilding back home.
