This is a real handy item. It is easy to install, and operates smoothly. Took 15 minutes to install, although I would suggest that you pre-drill the holes for better alignment. I can lift the lid while the box is stationary against the side of the truck bed, and it swings out over the tailgate with ease. My retractable tonneau cover is not in the way at all.I gave this box five stars even though it came damaged. There was a big crack in the lid. I did not notice the crack until I had installed the box, as the cracked lid was not an impediment to its installation. But, as it lifts right off its hinges, when the replacement box arrives I can just lift the broken box off its hinges and install the new one in about 30 seconds. There was no problem in ordering a replacement box for the broken box.You might want to get the box's inside measurements. I was hoping to store my tool case in there but the tool case was too big. My trailer hitch and insert (23 pounds) fit in the box with space left over. It seems incredible, but the darned thing will probably hold 75 pounds.I am evaluating whether I should buy one for the other side. It is a bit pricy considering the amount it holds, but it will hold a lot of tools, and would have held my tool box had the tool box been configured differently.The replacement arrived today, safe and sound. It took less than a minute to exchange the boxes, including unloading my trailer hitch. I still highly recommend, and caved in and bought one for the other side. Arrives in four days.
