Replace Thetford Aqua Magic Style II with Dometic 320?

I upgraded the JUNK Thetford in our 2012 Montana 2 years ago to the Dometic 320 w/sprayer and last Fall after negotiating our 2018 Montana purchase I told dealer OK if he would install Dometic 320 w/sprayer in new unit. Best place to purchase 2 years ago was PPL Motorhomes. $198.00 no tax and no shipping cost.

I posted last summer about a bad experience while camping in Bryce. My Thetford Aqua Magic Style II toilet overflowed and I was lucky to catch it before any real damage occurred. Assuming it will fit (have to measure), I am leaning toward replacing it with a Dometic 320. Oddly, the model with sprayer is less costly than without (on Amazon). Any thoughts here? Has anyone else made this or a similar upgrade to a Dometic 320? The other option would be a Thetford Aqua Magic Style Plus. But, with my poor experience with the Style II, I am leaning toward the Dometic.

We replaced our 2001 toilet for the brand you have. it was a bad move because of the water valve poured out the water before one year was up. We changed to the 300 series Dometic with out the spray.

Do a You Tube search on how to change the water seal on the dometic and it will help you decide. Have not needed the wand.
We bought 2 water valves for the Aqua at $45.00 each.

All you need is 10.5" for the Dometic 320 to fit. Do yourself a favor and get the one with the sprayer. Trust me on this one. I didn't, then after doing all the research, I returned it and got one with it and glad I did.
It's easy to do. One thing I did that helped me was after turning the water off and draining the toilet, I removed it by sitting it into a big plastic bag in the shower or hallway. Then I took a pair of channel locks and clamped them gently around the base of the water line coming through the floor. You don't want it to slip through the floor and have to take down the belly. I then cut off the factory connection and installed a Sharkbite connector that was a 90* elbow and standard 1/2 inch male threads and put in a 1/2" braided water supply line from the connector to the toilet. Some people put in a water shutoff here too as well. Then make sure the flange is set and tighten the bolts alternating sides and you are done. Turn on the water.
