I've ripped off a few plates that hung below the frame of the trailer when backing up a hill that gets steeper suddenly. I think that the "Shenkel HInge System" would cure that idea as well. Nice work Steve! I am also in total awe that you are waiting for the summer heat to tackle the keel!! I'm over here working frantically 'cause I'm deathly afraid I won't have things done before the heat sets in!!! Heck, at the rate that I'm going backwards I wont be done for next Christmas! Sean
