I had a local upholstery shop add these straps to my cover, they are seat belt webbing with brass grommets, $45 for the straps. She stays in the barn so the only time I need a cover is towing, We went to Lake Wawasee in IN. for July 4 and it worked good, 4hr trip, max 70 mph. The straps just work as a back up to the snaps to hold the front down and hopefully keep it on. We are going to Norris soon, so that will be a good test. I wonder how long it will last. Also, I added the spare tire and holder I took off my old boat trailer.
