Had a similar problem and it was the rotating shaft on the slide valve that had a bad seal that permitted tank gasses to escape into the motor home. Ruining exhaust fan made problem noticeable and with all air inlet openings closed pinpointed the problem and made it evident. It is a non-replaceable part and I had to replace the entire toilet. Problem solved and running exhaust fan no longer sucked fumes down the stack and out the leaking seal.
Thanks. How could you tell the odor was coming from the shaft seal and not just the seal at the floor? Mine it backed up into a corner and you can't really get behind it to "sniff" around.
Also, it is the slide assembly that I replaced a couple of hears ago, so not understanding why you had to replace the entire toilet. I wonder if I got a defective one perhaps? I'll have to investigate further.
