Licensed, I think you got it. If I understood Tony correctly, there should be two extra folds or 90 degree bends. One at the top of the tank (from "V" to "V") and another at the base of the tabs that tuck into the back of the cab (this will complete a "Z" shape). I have not ordered my 2nd cover yet, but that is what I'm going to do when I get it. Before folding it over a straight edge, I think it would be smart to score an impression along the inside of the desired location to help it bend crisply. Use something hard but DULL, as you don't want to cut the paper. Honestly, I didn't get the part about folding the ends at the factory creases, as no creases exist but for the small "Vees". Does the face of the panel continue straight across into the cab sides, or return back 90 degrees at the ends of the tank? Tony, care to clarify? Why no instructions included anyway?
Thanks and good luck. P.S.- Let us know how you do with it.
