Having never towed anything on any vehicle I've ever owned, I find myself needing to (quickly) figure out the towing capacity of my truck.

Here are the specs I've figured out that I need, but being the "truck slow" guy I am, I can't see the "this is your towing capacity, idiot!" number:

Engine: 5.4L V8
Rear Axle Ratio: 3.55 Limited Slip
Tires: P255/70Rx17

Now, I have the original sales slip for the truck (I bought this as a lease-back), and it says that I have:

7200# GVWR Package
Trailer Towing Package

According to the f150 2007 owner's manual (which only has listings for Crew Cab 4x4 and SuperCab 4x4, not SCrew 4x4):

SuperCab 4x4 (132.5" wheelbase)
Engine: 5.4L (with 17" tires)
Rear Axle Ratio: 3.55
Maximum GCRW-lb(kg): 13000 (5897)
Maximum Trailer Weight-lb (kg): 7300(3311)

SuperCab 4x4 (144.5" wheelbase)
Engine: 5.4L (with 17" tires)
Rear Axle Ratio: 3.55
Maximum GCRW-lb(kg): 14000 (6350)
Maximum Trailer Weight-lb(kg): 8300(3765)

Crew Cab 4x4 (138.5" wheelbase)
Engine: 5.4L (with 17" tires)
Rear Axle Ratio: 3.55
Maximum GCRW-lb(kg): 14000 (6350)
Maximum Trailer Weight-lb(kg): 8200(3719)

Crew Cab 4x4 (150.5" wheelbase)
Engine: 5.4L (with 17" tires)
Rear Axle Ratio: 3.55
Maximum GCRW-lb(kg): 14000 (6350)
Maximum Trailer Weight-lb(kg): 8100(3674)

Now, I have no idea what my wheelbase is, nor what my GCRW is. From my VIN, I know that my GVWR Range is 6,001 - 10,000 lbs.

Any and all help is, as always, greatly appreciated. Thank you all in advance.


EDIT: Some additional information from my back bumper:

Hitch Type___________________Max Gross Trlr Wt(lb)___________________Max Tongue Wt(lb)
Weight Distributing 9900 990
Weight Carrying 5000 500

There is also a V-5 stamp in this information, if that makes any difference

Do you know what size your bed is? The SCREW is the Crew Cab, which at best, you can tow 8200lbs (with the shorter wheelbase). subtract 100lbs if you have the 6.5' bed (like I do).

Without measuring it, I believe the bed is 5.5ft.

If that is the case, you have the 8300 lbs. But measure to make sure.

With a bumper towing capacity of 8300 lbs, is it possible to pull a goose-neck trailer? How would I find the max weight I can pull this way?

I am new to this forum, but I wanted to tell for those who dont know, the difference between half and three quarter ton rear axles. In short of being a machinist for nearly thirty years here is what I have seen: There is a REASON that wood haulers do not use half ton trucks. All the weight is on the rear flanges of the car style axles. If overloaded, they will snap off and shove the wheel and tire up into your wheel well and you will have an instant 'dually' rear fender added to your pickup bed. This could result in injury or death of yourself or others especially at freeway speeds. On earlier trucks, say from the 70's and 80's a 3/4 ton had a full floater rearend where you could actually pull your axles out of the rear end and the wheels are still on the rig. A half ton cannot do this. Half tons have one rear axle bearing per wheel, 3/4 tons with full float rearends like a Dana 60, have two bearings per rear wheel. To save money, some manufacturers used a beefed up 1/2 ton single bearing style rearend and call it a 3/4 ton. You can tell if you have a full float rearend if the rear hub extends atleast four inches thru the rear rim. I offer this as a benefit to those who still think the difference is springs and ratings as I once did. In my opinion, half ton trucks with excessive springs are a deadly combo. I once loaded 5500 lbs in the back of a half ton and drove it sucessfully to the job site. I was also only 22 years old then, now 48. Dolphin mini motorhomes had a recall on their rigs due to this problem. they actually made dually rear ends on motorhomes and people were breaking flanges on the freeway and crashing. Multimillion dollar recall was the result and a 6000.00 full float rear end was the fix. FYI to those buying trucks. Get a strong rear end with bigger gears= much more truck for the money, or put a 3/4 ton rear end in your half ton as many do.
