Aight guys here's the rest of the story. Turns out it is definitely a QC issue. I went to the dealer today and swapped it out for another one (same part number) and it fits nearly perfect. The small hump on the left at the tailgate lays flat when you put a little weight on it. I'm assuming it will flatten out. The previous mat was like 3/16th to a 1/4 inch wider.
To answer the question of why bother when I have the line-x, this is to keep things from sliding around. The line-x isn't really grippy at all. I also wanted the extra cushion for my knees. Was it really necessary? No, but it definitely adds some functionality and comfort and I paid for it with my fordpass points anyway. Im very happy with the way the bed is setup now.
