Want to replace my Thetford toilet with Dometic 320

I bought my camper a little over a year ago. The Thetford Aqua Magic Style II that came in it is ok, but will randomly leak all the water in the tank and the camper begins to stink. After reading about swapping the seal not being plug and play I think I would prefer to get a Dometic 320 like was in my previous camper.

My flange bolts are 10" from the back wall. There is 1 1/4" space between the back of the toilet and the wall. I see the Dometic calls for 10 1/2" to the back wall. Am I out of luck, or is the space behind my current one enough for the Dometic to fit?

  • My seal leaks from time to time (don't they all?), but a good dose of white vinegar usually clears it up.
  • Yes, in the bowl where you expect to see it when you lift the lid. I have cleaned and used plumbers grease with no luck.

    Are you saying you have the Dometic 320?
  • I have the 310 sorry. the distance from the mounting bolt to the back wall is just under 10".

    Water in the tank? I'm not sure what you mean..I don't see a tank on the Thetford. You mean the bowl?
