For all those people who complain that the bolt holes are too close to the center, or that it was poorly engineered; READ THE INSTRUCTIONS AND LOOK AT THE PHOTOS. The square bolt heads are there for a reason. If you put them in correctly you will find that they sit up against the center part of the assembly which means you don't need a second wrench while tightening the nuts. It works perfect!The real trick is where to position the mounts on the truck, and that will be unique to each camper/truck configuration. It might be easier if you have an 8-foot bed, but on today's 6-1/2 foot beds it's a bit tricky to find that perfect spot to place the bracket and get it to mate up with the camper's attachment point.After you have identified the mounting point and it's time to tighten the bracket, hold the clamping plate in position, insert the bolts, start the nut and then push the clamping plate as high as it will go. Tighten the nuts from the back side (between the bracket and the bed of the truck). A ratcheting wrench works best, but a socket wrench will work just fine. You will need to alternate between the two nuts until they are equally tight. Adjust the depth of the spacer foot, tighten its locking nut and you're done!
