Man, just watched 3-4 more videos on this. I still don't see why it doesn't smell all the time, even parked in our driveway a week or two after coming back from a trip. If waste had built up in the inner cavity of the toilet why does the smell go away until we go camping again?
As to when the stuff gets back up there I guess it would be driving from the campsite to the dump station? We certainly don't drive around with a tank that is full or partially full.
