The installation instructions are poor to fair at best. The instructions could be made easy if each step would show the exact part (which it does) and the exact hardware to install that part (which it does not.) This was the biggest issue I had. It took about 3.5 hours instead of the 1.5 hours claimed. Also I did not have any air leaks when I finished. Now that I've done it through trial and error, I could write the instructions for them and save a lot of hastle for future installers.
