odor in bathroom .....and its not me.

We just returned from a weekend camping trip. We discovered a strange odor in the bathroom while taking a shower. I thought at first it was coming from the hot water tank...but then I did the dishes and there was no smell in the kitchen. I can't smell anything directly from the drain...but then again it is so strong I m not sure where it is coming from. I've read of the calgon thread and thought about doing that...is there something better I can add?

I just came back from a trip and after 3 days of 90+ heat I also had a bathroom oder that was strong. I dumped the tanks and closed the vent in the bath and that helped. I think the vent pipe was allowing oder in with the lack of any wind blowing.

Never thought about the vent...we always have it open.

There is often an air admittance valve on a stub off the drain after the trap on the bathroom sink. It opens and lets some room air in when you dump so the vacuum formed doesn't suck the water from the trap.
If the flapper doesn't reseal you will get odor from the gray tank - which smells pretty bad even if it is the gray tank.

The valve unscrews and usually can be replaced pretty easily. Replacements can be found in many hardware stores.

Very common to have odors from roof vents being drawn into the coach particularly if you have two open----warm air exhausting during a shower can create enough air movement to draw cool air in from the roof. I have those venturi things on my vents and it stipped that source for odors. Also in hot weather if you have a washer dryer the pee trap can dry out---just run the washer and it will fill again.
