Many early pop ups used a winch from the Goshen Stamping Company, but your best information will come from Jayco Customer Service, with the year, model, and VIN number. They may still be able to identify the winch company. It may take time to get the information, with the current condition of the country right now. Be patient, and welcome to the Forum.
