Dometic 300 toliet

[ScoutIV]

My dometic toliet in my interstate 19 is stinking really bad.

After watching some you tube videos it appears that this is a common issue with this elcheapo thing.

Has anyone replaced this with a better one?

We replaced the all plastic Dometic on our 2023 Interstate 19 with this one that is low profile and has a porcelain bowl: https://www.amazon.com/dp/B002UBZI6S/ It doesn't creak or sound like it's going to collapse when you sit on it.

The smell could be your toilet (the flush valve in the base could be leaking and allowing odors out of the black tank, or it could be the gasket that sits between the toilet and the tank inlet.

Is the bowl holding water?
Sometimes a tank just needs a good cleaning especially in hot weather. When our tank gets el stinko I will put 10 gallons of water and some original Pinesol and shake it up a bit going down the highway. El stinko will be gone.

Removed the 100% plastic toilet and found that waste leaks into the inside of the bowel as it flexes when you sit on it and the seals for this allow the leak.

Ordered a replacement as suggested. This has a one piece ceramic bowel.
