Hello Susanne, thanks for reaching out. We should have the toilet seat you need, but toilets are not make and model specific to the RV, so there is no way to confirm exactly what you need based on just that. The replacement seats are more brand and model specific to the toilet itself.
For example, the Replacement Toilet Seat # LC48AF you were looking at is for the Dometic 320 RV toilets, and the Lippert Flow Max RV Toilet # LC67AF.
I went out to our warehouse and measured the seat. The seat itself is 17-1/2" long and 14-1/4" wide, and I edited a picture to help illustrate. If you can confirm the seat size, or brand and model number of your current toilet, we can match those up and make sure you are getting the right thing.

I have a 2021 Riverstone and this toilet seat fit perfect. It is all plastic, no wood. I actually prefer it as the wood gets stains and doesn't like harsh cleaners melting the paint adding to the stains.

The slippery swat is light and snaps off and on fire easy cleaning, fits well on the dometic throne. To sit to sit or stand on closed. Like it better than the original.

This seat fit perfectly, the color was little off, but it's just a toilet seat.
