Here are some RV tubs with seat. Searched for using Bing because I hate Google.
Looks like the black pipe sticking up has an air admittance valve.

It acts as a check valve by allowing air into the pipe. There is a rubber seat the closes to keep stinky air from coming back into the trailer from the black tank.
