In the old days..... After flushing my RV's toilet, I used to smell "stank" from our toilet as well. Not all the time but once in a while. To eliminate this smell, I simply created / installed a 12V computer fan "power vent" system using ABS Piping on the RV's roof top stink vent pipe. Something that looks like:

For this mod, we simply turn the 12V fan on before going to the washroom, flush the toilet, wash hands and turn the fan back off. When fan is on and toilet valve is open, the "bad smell" is sucked down - into the holding tank, then sucked up the holding tank's vent pipe. Thus, no more smells coming "up" the open toilet valve (when one flushes).
If into a store bought product, simply buy their new 12V power vent system and install within bathroom's inner wall cavity (and using an access door). Or, install in the RV's roof cavity area. re:
- click here - If wondering, my new RV will have this 12V power vent product as well. IMO, this product (or something like it) should be mandatory factory build. That's how great it works...
And best of all, NO more chemicals down the toilet valve opening either. Money saved from no more chemicals paid for this 12V fan product many times over. And, we all love saving dollars on maintenance tasks...
Hope this helps.
