I have an older Frabil XL Twin and they don't make covers to fit it anymore. I bought a $5 tarp, laid in on top, cut it to size, hot glued the edges doubled over and put grommets around it on the doubled edges then ran a $2 piece of elastic (bungee type) cord and tied off. It works great and sheds snow well. Never had it blow off even in high winds towing behind ATV. Sorry but can't figure out how to post an image.
