I also registered an old trailer with no title as homemade. Part of the trailer had been cut away and rebuilt. There was no VIN. I just had to get a state police officer come out and make sure the new VIN issued was attached properly. Make sure there is no old VIN on the trailer if you go the homemade route.You can register the trailor as homemade. A friend of mine went to fast tags with his used trailor from Florida which had no vin# and got tags for it as a homemade trailor. He said it was a quick and easy process.
