Query: Almost the perfect cover

I bought this to replace my worn-out OEM cover and couldn't be happier. The cover fits the bed perfectly and hasn't leaked a drop of water over the course of the year I've owned it. This is using a below-the-rim bed liner. The securing mechanism is a simple simple but effective set of four cam-action clamps that fold up and out of the way when you fold the cover for access to the bed.Intallation took about 30 minutes, 10 of which was pulling it out of the box. In practical use, it takes about 1 minute to open up the cover and lock it out of the way giving you access to 2/3rds of the bed. It takes about 3 minutes to pull it completely off for access to the entire bed.The is a huge improvement over the little P.I.A. bendy clips that the Toyota OEM cover came with.The build quality seems good. No tearing, seam gaps or frayed edges. Time will tell how well the fabric will react to UV, but so far, so good.
