Toilet Replacement for a 40U

MayorWest76 · 01-09-2023, 03:16 PM

I have a 2014 Itasca Meridian 40U and I would like to replace the original Thetford Style II toilet with another brand. I am looking at the Dometic 320, this one has an elongated toilet and I am not sure of the fit. Has anyone put this toilet in and how do they fit in relation to the very small area and closing the door?

Any and all suggestions are welcome!!
Thanks,

Since they are completely rebuildable, I'd go ahead and upgrade to the Dometic 510 commode.

Thank you for the reply, I will look to see what it takes to install. This looks to be a 4 bolt toilet and I would need an adapter.

My 40U has a shelf like cover running along the outside wall and to the back of the toilet. Consider this when replacing the toilet. It might interfere with the water hookup and the flush petal. Also check the height of the toilet. I had a coach with a high toilet. I'm short. Very uncomfortable.

I have a 2011 40u, and replaced my toilet about 4 years ago with an elongated model from camping world. I am not sure about the specific difference in size, but I know that I measured it while at the store to make sure it would work. The install was done right in their parking lot, per their parts guys since they were too busy. It probably took a total of 40 minutes, including getting my tool out of the basement.
I’m 5’ 10”, 226, and I had a problem sitting with the door closed on both units. It’s a poor design for an ave sized person, but that’s the setup the wife wanted. My next coach, sit on the toilet and step into the shower…
