Hey Tim,

There unfortunately isn't a slow close seat option for Dometic's 300 series RV toilets. You would need to swap out the 300 series toilet for one of Dometic's other series that does have a compatible slow close lid like the 310 # DOM57FR, which would come with a slow-close lid. The seats/lids are all series specific and come in varying sizes so they unfortunately aren't as interchangeable.

Hey Tim, did you end up switching to the Dometic 310 toilet with the slow-close lid? Knowing how that upgrade worked could help others looking for the same feature.
