Took me 1 to 2 hours because I take my time and checked several different YouTube installation videos etc. if I had to do another one it would take maybe a half hour. Awesome cover!

Shipping and packaging were excellent. I would have preferred a hard copy of the installation instructions, but the videos were well done and helpful. Thankful to be able to work with NAPA!

Great cover. Seal around the tailgate is a little weak and lets water in while at the car wash.

Looks great and appears to be well constructed. I am 69 and installed it by myself. Sprayed it down with water hose....no leaks.

The cover looks great. You need a second person to help you with the rails, just to make it easier, but I eventually did it by myself, but a third hand would have been nice. I wasn't a fan of the instructions or pictures on them, but I worked my way through. Overall, the install wasn't bad. Do drilling required, which was important for me. I like the sleek look and the security of the cover.

First, I like the product. It’s my second one. I had one on my previous F150. Installation was pretty straightforward. There were videos, but no written instructions, which I didn’t like. My MX4 came with a few extra parts that I didn’t recognize. There were no mention in the videos. I decided to email the manufacturer, RealTruck. I described the pieces and awaited an answer. My answer from the multinational corporation that sells a consumer product over $1000: “contact Napa where you bought it.” I was shocked. There was no attempt to try to answer the question. One simple sentence. For that reason, I cannot recommend the product. Choose another product that Napa sells with better customer service. I’m still shocked and disappointed in RealTruck. Napa was great. Shipped fairly quickly and it was in good shape when it arrived. Napa: recommended. RealTruck: not so much

I’m disappointed in the cover, I watched the video and installed it like they said on the video. And I have adjusted it several times but I’m still having problems with it leaking. i’m at work right now. Don’t have time to send pictures, but I will send pictures of where it’s leaking when I get off of work.

This is the second BakFlip I’ve had - the functionality is great and setup took just under an hour by myself. A bonus was that I was able to save 10% on the order!
