We always open ours up at the dump station and rinse it at least one more time. It only takes a couple of minutes extra to open the TM up and close it back down. We usually keep a 2 1/2 gallon bottle of water in the TM that we fill up ahead of time for filling up/rinsing out the toilet a second time. Whatever extra we need to make it circulate we pump out of the water tank using the shower hose.

When we have full hookups we rinse it out twice.

To us, it's not that big of a deal. We plan ahead for what we need to do and it saves a lot of time.

Another option would be to bring along a blue tote, you could make the first dump into the blue tote and then fill up the toilet before you dump a second time. That way you wouldn't have to open up the TM. Or, you could dump the TM and then fill up with a "mini charge" and some tank chemical after you get home. That would also help eliminate odors.
