If you are running an exhaust fan, kitchen or bath, air will back-draw from any trap or seal that is not tight. Be sure your toilet is sealing, will it hold water on the slide when not in use?

Guessing but perhaps air intake for A/C and the ambient breezes. When wind is right and A/C on, wind over the roof vents blows the vent gas toward the air intakes.
We had a similar problem when going down the road in our class C. When I rolled down the drivers window it created enough of a differential as to suck the vent gas back into the coach. Smell would go away after stopping so had a heck of a time finding the cause.
Same with us , we have to keep the drivers window up.

We had this problem in our 2006 Suncruiser. Turns out that the ac duct system from the basement ac unit up behind the rear cap had a leak. As it was pumping air out it in turn was causing negative pressure in the coach. This would pull air in the coach from any where it could. In my case it was many places including the smelly holding tank area. Put a plastic bag over the window with the it down ac running and see which way it goes. If in than that could be it.
