Horse and livestock trailers are titled like any other recreational/utility trailer above the state weight threshold using the trailer’s VIN, typically classified as "horse trailer" or "livestock trailer" body type. Gooseneck trailers usually require a 1-ton tow vehicle and may need commercial tags in some states.
