Just bought a 1989 Jayco Po-pup last summer. After our first trip we set it up at home and a strong wind came up and actually blew the non door side of the canvas so hard it broke the plastic piece that hold the canvas in place. I am hoping someone can give me an idea how to repair this or where to get a replacement part. So far I haven't been able to locate anyone in my area who does work on pop-ups. Thanks.
