I have a trailer that is used for racing. About 44', enclosed. When I bought the trailer from a person that was supposed to send me the title in the mail. I paid cash. He also bought my smaller trailer and I agreed to send him the title for it when he sent the title to my new trailer in the mail. He never did send the title, and now I am not able to get in touch with him. How can I get a new title for this trailer??
