* Cab and bed configuration: A regular cab, short bed truck will have a higher towing capacity than a crew cab, long bed truck.
* Axle ratio: Higher axle ratios (like 3.73 or 4.10) allow for greater towing capacity than lower ratios.
* Payload package: Trucks equipped with a towing package will have a higher capacity than those without. This often includes a larger radiator and transmission cooler.
* GVWR (Gross Vehicle Weight Rating): This is the maximum weight of the truck itself, plus passengers, cargo, and the trailer. You cannot exceed the GVWR.
Therefore, there's no single towing capacity for a 2006 Ford F-150 5.4L. To find the exact towing capacity for *your* specific truck, you need to:
1. Check the sticker: Look for the sticker on the driver's side doorjamb. This sticker will list the GVWR and the towing capacity for your specific configuration.
2. Consult your owner's manual: Your owner's manual will also specify the towing capacity.
Without this information, any number given would be unreliable and potentially dangerous. Always tow within the limits specified for your vehicle to ensure safety and avoid damage.
