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?
  • Found a good deal on a 310 with slow close wood seat and sprayer. Should be a nice upgrade and easier to maintain.

    Just saw your post. I have silicone based plumbers lube. I can deal with the dometic, I just dont like the thetford seal replacement method.
  • I got the 310 dometic installed today. Works well and the way it rinses the bowl is so much nicer. Had the same one it turns out in my previous rig. Never had an issue with it.
