Sulfur smell and NOT from drains...

Ok, I have read and searched for a while now....I cannot seem to pinpoint the issue I am having so I am throwing it out here. If I missed a "thread" on something like this, sorry, please point me to it.

When I run water in the sinks or tub, I can stick my nose near the vent below in the pic and WHEW! it'll knock your socks off....No idea where the odor is coming from.

I can confirm its NOT coming from the drain. Its coming from that dark hole in the other picture which is the underbelly. Where in the WORLD would that smell be coming from.

I know its not the Air Admittance Valves under the sink since I checked them both with my nose. .

This is the picture from the other side of the tub, yes I know the lines are backwards...FR dopes, I am going to fix it later.

This one is looking down into the whole from the picture above.

Thanks all.

You probably need to sanitize your fresh water system. Sulpher or rotten egg smell can come from a fresh water system that needs sanitizing. Put some bleach into the fresh water tank along with some fresh water. Pump through the system and let stand for a day. If you can, take the camper for a ride so that the water has a chance to slosh around and get the whole tank. You can then drain and refill your fresh water and should be OK.

Have you checked your battery? a friend of mine recently had his power converter go bad, and it was over charging his battery. The smell of sulfur would almost knock you over.
Just a thought...
