Velcro strap...I had to do the same on my Jeep with the top down.

I agree. I had a 2 door Rubicon with a soft top and the view out the back is not good when the top is down. This is a better, functional design. My only question is if it flaps around when it is open on the top. But guessing if it does that a few bungie cords will control it.
Mine is in boxes...
Same.
At first I didn’t like the folded top on the top but it is actually more functional. I had Jeep 2 door and the soft top folded back blocks visibility. The trektop design is better in this way.
