Vent under sink cause of smelly trailer?
My trailer smells gross come summer time. Was gone 3 weeks and come home to that sewer smell. To me it smells like gray tank. Pretty sure my P traps are still filled with water. It must be the kit...

When was the AAV added to the standard?
I don't think my 1990 Winnebago has one.
You may not have an AAV if the kitchen sink is close enough to the vent pipe to the roof?
