This is why I started this thread. I did use powder chemicals and will just add more on my next trip.

That is interesting, with the black tank valve closed and the ball valve on the toilet sealed you shouldn't be getting a wiff of anything coming from your TT. Unless it is coming off of the venting outside and then being blown in through a window.
I was just making sure you hadnt camped with full hook ups and left the dump valve open for the black tank, this is a huge no no.
What I do is i use the powder TST or the "blue goo". I add 3-5 gallons of water down the bowl when adding chemicals. This dilutes the chemical and creates a "water trap" so when solids go in there is water to "encase" it. Doing this I have never had a problem with smells.
