True Description of TM Toilet system

Howdy,

We are current owners of an Aliner LX. We have put many miles on our rig and have all good things to say about it. As we advance in age, we are looking for a bit more room and, of greatest priority, a bathroom. We know the new Aliner Ease has a BR, but we would like a tad more room.

The TM 2720SL looks like just the ticket for our needs. I have read various threads and still do not quite understand the toilet system in the TM. Can someone slowly walk me through the set up? The "recirculating concept" almost seems to me to be a porta potti. If there is no black water tank, where does the waste sit? My other problem is we have never seen a TM "in the flesh" so to speak. Perhaps if we did, we would better understand. We are hoping to do this when we stop in at Auburn RV in Wash. state later this month. Thanks in advance if someone can help.
