Hey Luke! It may be possible to replace your Dometic 300 series with the Seaflo Ceramic RV Toilet w/ Sprayer Attachment # SE42MR but you will need to measure to be sure. This toilet requires a rough-in measurement of 10" for installation. This is the distance from the wall to the center of the door flange, see the attached photo. If you meet this requirement you will be able to install the Seaflo in your trailer.
What kind of trailer do you have?
