I might be one of the few that likes my Rampage. It HAS given me a couple problems over the years, but they made it right. There are some small straps that help hold the back window in place. They rotted by the second Summer I had it. Rampage REPLACED the entire top! After a couple more years, the center strap broke, but it was a simple matter to replace it.
Overall, the top is still snug and tight. No leaks, no damage to the fabric of the top. I've had it for six years now, and don't see myself replacing it any time soon.
