Me thinks you have a major problem.
The post you quoted was talking about the design and operation of the sewer system AT THE CAMPGROUND, not in the trailers.lanerd wrote:
When stuff is flushed, it should not allow any sufficient amount of air to come back up as the pressure it creates should cause the air to go up the vent...not up the toilet at the same time. That's the whole purpose of the vent.
Please try to explain to me how the TWO open pipes will not share any back pressure that exists; especially how the larger one won't take more during the time that it's open ???? HINT: The laws of physics are at work here.
The vent is there to prevent the BUILDUP of noxious gasses.
What happens when you open the big hole varies wildly depending on wind direction, windows open, etc. Unless you have a power vent pipe with a fan in it......which I have never seen.Sam Spade wrote:

And if your roof vent is not sufficient to keep odors from entering the rv, then you have a problem with a seal, AAV, or some connection. Any wind going across the roof vent will automatically create a vacuum and pull the odors out completely.
Alas you have no control over how the sewer pipes are laid out, now they are vented and how many of the unused inputs are left open......and how hard and from what direction the wind blows.

It is not that unusual for there to be positive pressure in the system. Sometimes that pressure can be substantial and can get through places where there really is nothing wrong.....under normal circumstances.- When stuff is flushed, it should not allow any sufficient amount of air to come back up as the pressure it creates should cause the air to go up the vent...not up the toilet at the same time. That's the whole purpose of the vent.
Something is not computing here and it sounds like maybe your vent is not operating as designed. Perhaps the pipe is sticking too far down into the tank and is being blocked when the tank is full or nearly full. Just a guess on my part, but I do suspect you have something that's not working correctly.
With all due respect, I'm not trying to argue with you...just trying to point out that maybe you might look at this from a different angle.

Here's a clue for you Ron:
About half the time that I "flush" my toilet, I get a whiff of really unpleasant "air" coming back UP the pipe. I assume that this is partly because the fermenting creates gasses that are lighter than air.....and partly because the mass that goes IN will push air OUT.
Anyhow, unless and until you can convince me that my nose is broken, I will continue to use something that covers up that odor.....even if it does nothing else that it claims.- Yep, it is.

Ron - Yep, when we started rv'ing we did use those little chemical packets and fabric softener. This past year I've used only water and have had great results. Not one whiff of what's in the black tank is ever smelled, even when holding the toilet valve open. I'm guessing my system is working like it should.
- Have you ever just tried plain water without chemicals? Do a search here and I think you'll find many, many experienced rv'ers only use water.
FWIW, I would never allow my black to to get completely full....as soon as my 2/3 light comes on, I dump. And we also (this is getting a little personal) flush the toilet while still setting on in as the body "sorta" acts as another seal.....and then turn on the fan after we flush.
You know, to each his own and what ever works for you is the right way to do it. It's your rv and your money.
Happy trails...
Ron Why in the world would you hold it open???
It was meant for it to be a to see visual "example/test" for the RV'ers that do NOT know that the toilet is straight open NO p-trap. :R
Here to tell you. I use chemicals. For years and years no smell. UNTIL I RV'd to Florida in the summer at a site where I had to break camp to dump so I would wait until full.......AND...if you allow the tank to completely fill up, the odor DOES come into the RV when you flush. When you open the flap to dump water just trickles down the side. The time it is open and the time it closes to fill IS enough time for odor to enter the RV.
Again filled tank, 90 degree weather and sitting for days in tank before dumping. Many of us who RV in those conditions will use 2 bottles of chems in that situation.Sam Spade wrote:

In reality almost everybody uses "chemicals" of some kind.
Where some get the idea that detergent and water softeners are not "chemicals" is somewhat curious. :h
I know I've never said that and I don't think anyone else has ever said soap and softeners are NOT chemicals. It is intuitively obvious that when rv'ers speak of rv chemicals, that are referring to the rv chemicals that are designed to mask odors.
