First, everything I needed was in the box which came when it as promised. I watched a few YouTube videoclips while I while I waited for the cover to arrive. I installed the cover by myself with no problems but a helper would have gone faster. The cover looks and fits great and well made. One complaint is the latch pull release is a little hard to release but may improve after use. My biggest question is how water tight the cover is going to be??? Let you know soon.

Overall I'm pleased with my BakFlip MX4 truck bed cover. I have a 2018 Nissan Frontier, short bed. The cover was delivered exactly when promised, it took 6 days to come to the San Diego area. There did not have any visible damage to the box. It was really easy to install, I did it myself with no one helping me. I never felt the need for help, it was that easy. It fit perfectly.I was surprised how well it fit right out of the box. There was no tweaking to get it right, just boom and it was done. I'm very pleased with the final product, it really puts the finishing touches on my truck. I've already had several positive comments on it's appearance. Now for the other story, I have 2 what I would call minor issues. 1. The two front corner covers were broken off when I opened the box. I assume that was from shipping. Even though the cover was packed and padded really well, those front corner covers are in a vulnerable spot. They are just plastic and have tabs that push in the metal frame. Under normal conditions after the truck cover is installed, they are protected by the bed of the truck. I think during shipping if the package is set on it's end, the cover could shift and break off the corners. When I get new ones, it is a simple process to attach them. Maybe the manufacturer should look at better protecting the front corners during shipping. 2. On the right middle hinge there was a small tab that had pulled out of what looks like the hinge frame. I don't think it was broken, just pulled out. It made a bump in the rubber seal that runs the length of the right side. I lifted the side of the rubber seal and reinserted the tab in the slot where it belonged and the bump went down. So far it hasn't pulled out, so I will assume it is fixed. Again, even with those two minor problems, I am very pleased with the quality and appearance of my truck bed cover. The price is not bad for the quality of the product. I'd buy it again if had to make that decision again.

This is a very well engineered bed cover. I was surprised how well it fit the Tacoma without modification. This is the second BakFlip I own. The one for my full sized Ram fits and operates just as well.
