Fiberglas? Hummm My 07 fenders are all steel. Wonder if someome replaced the OEM ones. The 5.9 was a wonderful motor, but suffered at least in the automatic versions with a 4 speed auto and no EB. My 6.7 has a wonderful 6 speed auto and factory EB which will bring down my fully loaded fiver on a 6% down grade easily without the use of much service brakes.
You might ought to go out and try to stick a magnet to your dually fenders, they are fiberglass. The steel one piece bed and dually fenders did not come out until 2010.
