Excellent quality, easy to assemble the panels, all hardware included, shipping was exceptional as was the packaging......... I would have gone with 5 stars had they included installation instructions. I watched the Youtube video of how to install this in a Gen5 4runner (which is much more complex than a Gen4) and that was helpful yet not needed as I am very competent, and did not feel instructions where needed. Now, I know not everyone feels the same way, and not everyone has the same skill level, so a basic instruction for each Generation would be my recommendation. If you have a Gen4 this is VERY simple and self explanatory to install, do not be afraid.
Now that the panels are installed, I have no complaints whatsoever. I'm impressed with how sturdy the bridge platform really is. I also highly appreciate the spacing of the pre-drilled hardware; not only does it fit ram mounts (one of my mounting solutions), but also other brands too. Similarly, the spacing of the windows on the panels made it super easy for me to mount other tools like a CB radio. Looks super clean.
As the review title suggests, I wish there were better directions. There was nothing at all in the box besides the product and a couple root beer candies (nice touch all the same). If I had directions, my install experience would have been much better. Similarly, when I looked up the install video online, it pointed me to a 5th gen 4Runner whereas I own a 4th gen. When I called customer service, they said I should be able to figure it out from the other video.
Overall great product, but for five stars I sure wish I could have had a bit more install support. I like to think I'm not too dumb and it wasn't totally transparent to me how to put it on.
