Mine was on my old truck when I got hit head on and held up fine. It's currently on my NNBS. The rivets that hold the hinges on are a bit rusty but not much. The top got dented in a hail storm. And the rear panel has a bit of warp lately. But I've had it for almost 3-4 years now and never did any PM on it. I also had to do some minor modifications to get the NBS model to fit the NNBS with bed liner. Overall it's a great tonneau. I would definitely buy one again.
