I think you’ll be pleased with it. I get compliments on it frequently, everyone seems to like that it’s very low profile and made out of a heavy cloth like a convertible top. The tensioner works well, I’ve never had to readjust since putting it on about a year ago. As for leaks, I get a bit of seepage in heavy rain around the tailgate corners, nothing extreme. You will notice water pool in the middle of the cover in a steady rain, but it’s never stretched it out of shape, and as I said, I’ve never had to adjust the tension.
The only thing you should know, and it’s really not an issue for me, is that if you have the power up tailgate, you will need to leave the cover released before closing because it will usually pinch the seal and not close. I just make sure I latch it AFTER closing the tailgate. It doesn’t interfere with the power down feature.
