Stop shopping and buy this one.
I did a lot of research before deciding to buy this trail cover. Even then I was unsure until it came in and I installed it. It goes on in less than 5 minutes, by your self, and with two people I honestly think that it would take less than a minute. It has elastic straps, pull straps and plastic strips for the belt rails on the side window area to hold it tightly in place. It also comes with a carry bag. Sat over night with a small pool of water on top after a rain and no seepage.
