Will a Dometic 320 fit in a 2019 3811 ms

[bobder41]

Need some advise if a 320 will fit. I have an early 2019 3811 ms with the Thetford toilet and it is a constant maintenance or repair headache. I have had the Dometic toilets over the past 40 years with a lot less problems.
The 3811 ms has the toilet mounted at a 45 degree angle in the corner of the bathroom and the measurements are close.
Has anybody made this change in their 3811 or in a similar model with the toilet mounted at a 45 degree angle and what problems did you have? Thanks in advance

Mine was a perfect fit, but I'm certain if you find 3 models the same, the plumbing dimensions will NOT be the same. The Dometic web site will give dimensions for you to make sure.

As long as you can have the 16" from front of base to wall at the rear AND no door swings that will hit it you will be fine. You will like the 320 much better.

We installed the 320 in ours, it fits.

Bought it, went to install it and discovered When they glued and screwed the flange it was turned to far in one direction. The back of the toilet was up against the sliding door, after a trip to Lowes I found a flange adapter that allowed me to turn the toilet. Now it misses everything and works great.

I changed mine to a 320. I have a 3810MS. A slight modification to the flange and it fits fine.
