Yes, shauniscndn is correct, I purchased the top through Soft-topper.
It was one of my best additions to the truck. It functions flawlessly, easy to operate, no wind noise, and it is securely fastened to/seals the bed. I installed it in my garage in about an hour with basic tools and a cordless drill.
My only "complaint" is that visibility is limited when backing up due to the lack of windows on the sides. Its not a big issue and something I just deal with.
All in all I'd give the product 5 stars and would highly recommend it.
