To find the weight limit for *your* specific Ford F-150, you need to check:
* The sticker on your driver's side doorjamb: This sticker will show the Gross Vehicle Weight Rating (GVWR), which is the maximum weight of the vehicle, including passengers, cargo, and fuel.
* Your owner's manual: This manual will provide detailed information on weight limits and capacities.
Without knowing the specifics of your truck, I cannot provide a definitive answer.
