I think the one under the vanity is bad, and I don't see one under the kitchen sink.
I started the geo method as stated above before heading home, so it should be pretty clean now.
What is still strange to me is when I turned off the BR ac the smell quit coming from there. Anyway its going to the dealer in a few weeks for a checkup, since they installed the ac unit.

Had same thing. I just a dip in the sewer hose. Like a p trap but not so wild. The water in the sewer hose stop all sewer smell from comming back into the camper shower sink. I leave them open and tolet / black tank closed dump that when it gets close to full to flush solids out. Campesite sewers push air back up your sewer hose. Had this happen at my home rv dump into my sewer system (not city sewer system) i have a old system for my home sewer system.

You're overcharging a battery, you get a STRONG sulphur odor from that.

Start out with a mostly discharged house battery, the chassis FIXED VOLTAGE charging system will quickly result in battery out-gassing.

Check the battery water level, it might seriously "boiled" off.

The smells of sulphur and sewage are two completely different things. I'm sure th OP would have mentioned a rotten egg smell if the battery was the problem.

Strange....

Years ago we rented a decked out bus, with driver, for a family trip/get together.

Not long into the drive the odor of sewer gas (or so we thought) resulted in the driver finding a dump station.

But the odor persisted...

Then the engine stopped.

Emergency service arrived and quickly discovered that the chassis battery (diesel engine) was seriously outgassing due to be overcharged.

The over voltage had burned out the engine ECU.

Sad ending to our trip.

I had the same issue and it ended up being my galley grey water tank. I have a dump station at my house and when I dump while still connected to the TV my galley tank doesn't empty completely. I had no idea this was happening. After a few months we were getting a terrible "black tank" smell. I went through a lot of frustration finding the source of the stink. I had no idea a grey tank could smell that bad.

May be time to re-grade your pad so the tanks drain better. :-)

The air admittance valves in our unit went out right after we bought the RV, We need to replace the one for the galley tank again. They just do not seem to last long. They are cheap though.

Pretty good reason why. A good one that WILL last is around the 20$ mark. Pretty sure that will never be OEM in an RV.

This. Also try using The geo method to manage your tanks. I used to get really bad odors on my tt until I switched to this. Also, make sure you always keep some water in the black tank to avoid the dreaded stone mountain from forming.

A smoke test would be the best method for sure.
The bath fan was making it worse, so I just run it now after a flush.
Just got back from CW with the aqua kem I used to use that worked ok, and will drain, flush, and re treat.
I also put Teflon tape on the w/d drain plug since we don't have either, and will check the kitchen sink air valve.
Thanks
