I have an American boat trailer that I am trying to get registered. I have the title and bill of sale, but there are no vin numbers stamped on it . I took it to the DMV for inspection and they would not register becouse they could not verrify vin numbe. Has any one in nevada ever experiance this and if so what did you have to do about it? They don't want to hear that maybe back in 73 they probobly didn't put any numbers on the trailers.
