Seems like you have the same kind of trouble that I do, I just love it when I am discussing a problem with a mechanic whether it be boat,car,truck, or trailer, and they say "DAMN, I ain't never heard of that before!" Gives you a real warm and fuzzy feeling about the that is working on your stuff . Let us know when the light starts to shine on this black cloud that seems to be hanging over your trailer. Good Luck.
