Steve,
In a discussion with a trailer design guy, he stated that the pin high or low a small amount would change the pin weight very litte - so no problem. He did state that the greater problem would be that more weight would be placed upon the rear axle of a tandem axle trailer if the pin were high - on the front axle if the pin were low. He mentioned that "it depended a lot upon the trailer design" but that the difference could be 100's of pounds.
Maybe some day I will weight both axles and see what I find.
