Odor coming from drains in bathroom

My wife and I purchased and Columbus 340RK new in 2015. We love the trailer, the layout, the way it tows and its looks. However from day one when you turn on water in the sink or shower a fowl odor comes out of the drains. I put an inline trap seeing there wasn't one under the sink. This didn't much if any. And yes we have put deodorizers in the gray water. So here's my request. I don't think the stick vent is connected to the roof, ours seems to just come down to a plug and not connect to the drains. If one the other owners with a Columbus 340RK could do me a favor it would be awesome. while on the port side of the unit with the side storage door open take a look at the sealing maybe a foot inside on the sealing should be the bottom of the stink pipe that goes up thru the wall to the roof of the unit. Mine doesn't seem to connect to anything.

Air admittance valve either needs to be cleaned or replaced. Nothing new, happens all the time. Always someone asking on here about it. Just look up under your sink for the valve, screw off and on. Soaked mine and it was fine.

Search air admittance valve or AAV on the forum. Many discussions and photos if you are not familiar. This is a common problem, easily resolved.

Ditto.

The Air Admittance Valve looks like this:

I replaced mine with a Studor 20346 REDI-VENT from Amazon.

If I detect odors like yours, I check the air valve. I will also pour a cup of Hydrogen Peroxide into the drain and let it do it's magic on any bacteria or build up. I let it sit over night.
