Since i bought my f150 used i don't know if the towing package was included in the factory. I kinda think not because i only have the step bumper hitch on the truck. The owners manual says if the truck is not equiped with the towing package you can only tow 5000lbs. Does anybody know how accuate this is. My owners manual also says that for my truck. with the 5.4 engine 3.93 rear axel, super crew shortbed that it can tow 9300lbs.How do i determine if the towing package is added on.
