I just read Bill's comments on the proper use of the Thetford recirculating toilet:

We quite like the toilet. However, I will admit we do smell a little odor from the toilet, but to us it isn't offensively bad. As far as I know, we have used it correctly, used the bathroom fan, etc. I do think there are a couple of things at play here.
1) Any bathroom will smell when "doing business", but the bathroom can't be completely sealed off from the rest of the trailer, like any household washroom is. I suppose adding a Velcro skirt around the ceiling of the bathroom and sides might help with this, but we never thought this to be necessary. The fan will take care of much of this.
2) The Thetford toilet has a flexible plastic chute that self seals the sweet aromas inside the toilet. I have heard that this plastic becomes more rigid and is less effective. Some owners have replaced this plastic chute to solve this problem.
I suspect Bill may have upgraded his trailer before the plastic became rigid. In our high taxed country and expensive shacks that we live in, we cannot afford to drive vehicles newer than 10 years old, and trailers newer that 15.
Others have replaced that plastic chute very inexpensively and quickly. The only other issue we have had is that solids now stick to the sides of the bowl. I suspect that, with age and how it was used or cleaned by past owners, the bowl isn't as slippery to solids as it was when new.
In spite of the issues we have experienced, mostly due to age of the toilet I presume, we still find the recirculating toilet the best option. Other toilets require removing waste and walking it over to a garbage can. I am intrigued by the incinerating toilet, but I haven't heard much about the exhaust smells.
