Took my time on this install, and followed the video instructions as best I could, including the little pencil marks for the hinges. Doing this meant I had almost no problems getting the tailgate aligned, and it went together pretty easily. This thing is nice and sturdy, and I have no doubt it's going to last a long time.
The only suggestion I have for Turn Offroad is to include printed instructions. Videos are great for more clarification, but having to play/pause/rewind for each step gets old real fast. I really like having printed instructions that I can check off each step as I go.
