I'm going back comment to drjjj. I replaced the OEM toilet on our 2018 Monty. It works good and is far better that the original toilet. I had a 2008 Keystone Everest and replaced the toilet with a Thetford Aria Classic. It is a little larger toilet so measure for fit in yours but it had the most superior flush of the 2 toilets I have installed. I tried like hell to get the Aria to fit but this 320 is good. I need the sprayer though. That may get rid of me having to the clean the bowl every time.
