I have a 2013 f150 5.0 L 3:55 gears. Door sticker says gvwr 7350. Cargo 1599. When I go to the ford site for towing capacity it says 7700. Gcvwr 13500. If you take the 13500 minus the 7700 gives you 5800 not 7350. Or if you take 7350 gvwr plus the 7700 towing capacity gives you 15050 not 13500. Am I missing something?
