Hey Elliot, the Thetford C224CW # TH29UE has its own 2.37-gallon freshwater flush tank, but it isn't filled from inside at the toilet itself.
It is designed to be filled through an exterior water-fill door installed in the RV wall. The fill door is not included with TH29UE. It is Thetford part # 2379180 which is something at this time we do not carry.

The external locking fill door needs to be purchased separately. The wall thickness of my van was greater than the parts provided but the modification was simple. The things I like about this toilet are that it operates without being tied to my water supply and doesn’t require power. Best of luck with your project.
