What about that toilet?

How does the toilet in the TM work if using strictly at full hookup sites? Does it work empty into the sewer when flushing?

I have the understanding it is a chemical toilet like the Thetford and has to be dumped frequently. One reason for going with a TM (an upgrade from a popup) is the toilet/shower in them. If it is a normal chemical toilet there is not much reason us to upgrade.
