I had a local boat repair/upholstery shop make mine and am pretty happy with it. I use it when traveling and like the fact that the wind doesn't blow things in the passenger area around. I have a couple interior hold down straps that cuts down on the fluttering and even installed some aluminum struts on the underside for the same reason. These were improvements but I just live with the rest of the fluttering. Makes it better for securing stu4ff when stopped for the night or a meal. Of course, bad guys could just un-snap but out of sight, out of mind. Less temptation, I'm thinking.
BTW, I use "LIft-a-Dots" rather than snaps except along the tops of the doors, where I have a couple snaps. Didn't want to lay my arms on the pins for hours.
