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...

The AAV (Air Admittance Valve) does fail and is easily replaced. When it fails, it typically sticks open so that there is a direct opening to the gray tank and can really smell. Best bet is just to replace it... it's cheap and easy to installed and can be purchased at Home Depot, Lowes or even on line at Amazon.
Mine got neutered...
