Check to see if there is a serial number on it, it is usually up front on the tongue and usually by the ball hitch. If not, I would make sure there are no factory stickers on it and then bring it to the LSP and tell them you have a home made trailer that you need to get titled. Let me tell you from experience though, make sure you have safety chains on it before you bring it up there. I had to make a couple of trips before I was able to get mine titled. If everything goes well with them, the will stencil you new #'s on the tongue and issue you a title.
