I saw a post somewhere on one of these forums where an owner hitched the trailer, removed the weight off the jack, unbolted it, turned it to the next bolt hole and reattached. It really doesn't matter which way the head is pointing.
I looked at that but that results in a 120 degree rotation which in my case interferes with the propane tank cover. I’m going to drill new holes so I can rotate only 90 degrees.
