    In reality it could possibly be a leak on the trailer and what you're hearing is the air passing through the valve.... when does the hiss start? Is it steady hissing or does it start once you supply trailer pressure? Tractor?

    On the news the other day a lady driving her car down the hi way looked over to see a copper head snake next to her. She stayed as com as she could pulled to the side of the road and called for help. Thinks it had been in the car with her for over a week!

    I hate snakes & spiders and don't know if I could be that com to get to the side of the road with out crashing!
