FWIW that is a common way to keep the trailer's registration papers with the trailer.The PO had it on there as a place to grab when moving the trailer around.![]()
My TrailBlazer's new frame was built with such a extending tongue in 1994. I don't know that the PO ever used it. I've only ever used it when moving the trailer around the yard by hand.
