ANOTHER similar cause for foul odors can be a DRY BATTERY cell which puts out sulfur odor when rig is running/ traveling, because charging voltage to coach battery is HIGHER when engine running. CHECK BATTERY WATER LEVELS.
There is not doubt the smell is sewage, not batteries
Thank you for the ideas though!
