To address the tie down system I picked up some 1" nylon webbing and a bunch of snap buckles. They are very snug, easy to adjust, and very quick to snap on and off. The rocker guard makes a convenient mounting point.
To secure the back, I ran two straps from the corners to the center section, using the D-rings as mounting points. My idea was to be able to install the cover with the tire carrier open or closed - which worked fine.
But as soon as I looked at the result, I realized that the first time I installed the cover with the carrier closed, and then forgot and opened the carrier without disconnecting the straps - the cover would be instantly ripped to shreds (Yeah - that is definitely something I would do).
So I changed the path of the straps to use the taillight guards as the mounting point. Now no issue with the carrier.
I do wish I had thought of this first, as I would have changed the angle on the straps where they attach to the cover. On all my straps I used webbing as a backing to sandwich the cover fabric, so it will be plenty strong and will work fine despite the angle. It just looks a little funny...
