Hey Jurgen! A Dometic seat won't fit correctly so you need to stick with the Thetford. The Replacement Seat and Cover for Thetford Aqua-Magic Style II RV Toilet - White # TH34FR43XB is what you need. This is an exact replacement for the original seat, and is designed for toilets made after 2015.
What kind of trailer are you working on?
