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...

AAVs are required under NFPA standard 1192 which is specifically for RVs. They call it an anti-siphon vent device.
When was the AAV added to the standard?
I don't think my 1990 Winnebago has one.
