Review on Hard Folding Tonneau Cover - BAK BAKFlip G2 - Compatible With 2017-2018 Nissan Titan - Fits 5' 7" Bed (67 Inches) by Kevin Caldwell

1 - The clamps they sent do not work with the rail system. I had to remove the rails. The rails will work if I only use the bottom holes. However, the supplement instructions specifically stated to use the same holes, except for the middle one. The clamps sent could have easily have been shortened and widened to work with the rail system.2 - For this installation, the instructions said to use the longer bolts provided. The long bolts left 1.5 threads, so the nuts would not provided a secure grab. The washer provided would have prevented any nut from being attached.3 - Speaking of nuts.they weren't provided. I had to go to rush hardware store at 9:30 in hopes of beating their close time in order to get the proper hardware. 6 longer bolts and 6 nuts that actually fit those bolts.4 - The instructions for installing the rails were lacking. Perhaps this had to do with the incorrect instructions for the rail system and the fact that the clamps provided will not work with the rail system.5 - The video on the website provided 0 additional help. Unfortunately, there were not any good alternative videos on Youtube to assist with how these long clamps could magically defy the laws of physics and work with the rail system.6 - The hardware pack specifically said for Nissan Titan 2016+.Two points the positive side, once I removed the rails, went to the hardware store to get the proper nuts and bolts, and returned home, the installation only took an hour. Two, it looks good.I'm torn between 1 and 2 stars. If I didn't need the cover for a trip this weekend, I would have sent it back and gone with another manufacturer entirely. I'm only giving 2 because once I had everything, the install was easy. If Bak customer service has a decent response, I may go with a 3. However, I find it unlikely that I'll ever by a Bak product again unless their CS is so overwhelmingly good and provide appropriate hardware for installing with the rail system.Update - Downgraded to 1 star. I contacted manufacturer for replacement parts that would work with rails almost 8 weeks ago. They said that they would send. I've followed up 3 times. They have not sent and are no longer responding to emails.
