* Cab and bed configuration: A crew cab with a long bed will have a lower towing capacity than a regular cab with a short bed.
* Axle ratio: Higher axle ratios allow for greater towing capacity.
* Specific options and packages: Certain packages added to the truck can affect its maximum towing capacity.
* GVWR (Gross Vehicle Weight Rating): This is the maximum weight of the truck itself, plus the payload (passengers, cargo, and accessories). Towing capacity is reduced when the GVWR is nearing its limit.
Therefore, there's no single answer. To find the *precise* towing capacity for a specific 2009 Ford F-350, you need to look at the sticker on the driver's side doorjamb or consult the owner's manual for that particular vehicle. This sticker will provide the GVWR and the specific towing capacity for that truck.
You can also find general ranges online, but those are only estimates and shouldn't be relied upon for making critical decisions about towing. Always check the sticker and the owner's manual for the correct information.
