I had checked out the above movie before I bought my Dual Liner bed liner ($379). Took me just 30 minutes to install it. It's very easy on my knees when I have to crawl on it. Can't hardly tell it's there. They're both excellent products. If the OP doesn't have a bed liner, he won't go wrong with either of these two choices. Here's a video on the DualLiner: http://www.dualliner.com/video.php
As a side note, mud flaps are an absolute must have right from the git-go if you wanna keep those stones from scratching your new truck. My new truck didn't come with any. Dealer wanted $80 for 4 with the Ram emblem. Auto parts store had plane-jane ones (but very durable) for $10 a set (2).
Hope this helps.
