I‘ve had mine for a little more than 3 months and have been happy with with it so far and it fits my needs. I chose Peragon because it was the only locking hard folding cover I could find that didn’t obstruct the rear window when folded up and could be easily removed if I need access to the entire bed. It does a pretty good job keeping water out of the bed but it’s not completely water tight, which is expected. I also opted for the Platinum Package for the stainless steel hardware for longevity and quick clamps in case I want to remove the cover completely without leaving a trace.
There are only a couple quirks I can think of. It’s all or nothing when folding the cover and you can’t leave it partially folded up. It can also be difficult opening the cover if unsecured cargo slides to the front of the bed due to how it folds down into the bed. On top of that, mine wasn’t a straightforward install since I have the MFT w/o RAMBoxes. Despite what Peragon says, you CAN get it to fit with this configuration but you will need new aftermarket support brackets and extra washers.
If you haven’t bought a cover from them yet I highly recommend signing up for their newsletter first to get a discount on a cover. If you have the patience the deals get better as time goes on.
