I wouldn't even consider one without a small fan running continuously. Instead of venting up through the ceiling/roof as is done in most building installations, I vented mine down through the floor. The vent into the toilet needs to be tightly screened.
This not only keeps flies from laying eggs in the composting medium, but the slight airflow evacuates any smell as well as dries the content, preventing moisture/condensate build-up within the toilet.
Another benefit is that the evacuating air has to come from somewhere. One mine, the fit of the door isn't all that good, so I suspect much of it from this source. Mine also has the old style jalousie windows
with aluminum frames. Since installing the composting toilet, it is very unusual for any sweat to develop on the frames; or anywhere else, for that matter.
The result is not only a toilet that is odorless, but a entire trailer that is essentially odorless, even after a lot of cooking.
