I agree with post #2. No comparison between the Dometic toilets and the Thetfords. I pulled the Aqua Magic out of this trailer, brand new, as soon as I got it to my house. I put in a Dometic 310 because that's what DW wants. The 320 is elongated. The 310 has a rimless bowl whereas the 320 has a rim and they each have a different flush system - either one is much better than the Thetford. Note: the spacing for the units is different as well. I think (memory) the Thetford is 8" (?) from the wall while the 310 is 10" and the 320 is 11".
