Yup, had the same problem...took the small inner tongue out and worked it (read bashed with a hammer) to get it to work and seems fine. BUT one question I am interested in knowing and can't seem to find an answer is do people lub or grease up the coupler and ball (god I can see were this is going on this site). The trailer hitch ball seems a little scored from the coupler and am wondering if this is normal.
