Mr. Jensen,
Either you mis typed your info or you are wrong...better check your facts. When comparing GVWR: C4500 is 17,500, F450 is 14,500. I believe the Ford website has mis labeled the GVWR under towing as it should read GCWR. Big difference between the two. I was taught GVWR (Gross Vehicle Weight Rating) and GCWR (Gross Combined Weight Rating)
