Straps added to mooring cover, spare tire.

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.
