I just bought a new 2008 F-150 Supercrew FX4 with the 5.4L. I was wanting to know how much it could tow? I found on yahoo these numbers. How true are they?

Tow Capacity (Standard) 8300
Tow Capacity (Maximum) 9300

 

Look in your owners manual. It gives tow wight as your truck is configured, depending upon tire/wheel size, engine, transmission, and rear end ration. Also anything over 5k means you have to have a weight distribution hitch. Also your state will require trailer brakes starting at a specific weight.

You also need to stay within your vehicles GCWR (Gross Combined Weight Rating) when you tow. More than likely you will hit that max long before you hit your max trailer weight. GCWR is weight of your vehicle, weight of your trailer, and weight of all passengers and cargo hauled in the truck.

 

Well I dont see anything that says that. But I see.

GVWR Standard 7200
GVWR Maximum 7200
Payload Standard 1630
Payload Maximum 1630

Also this is my truck.

2008 supercrew FX4 5.4L V8 auto with 3.73 gears. Everything is stock. Curb Weight AT 5481.

 

Alrighty I got it, its the 145' wheel base with 3.55 not 3.73. So the max trailer weight is 7900 pounds.

 

I think you are looking at supercab, not supercrew.
Page 250 shows a 139" wheelbase supercrew with 5.4 and 3.55 and 17" tire, tow weight is 8600lbs, 18" wheels is 500lbs less.
GCWR is 14000 or 13500, depending upon the wheels. As your truck empty probably weighs around 5500, that leaves 8000-8500 tow weight. Subtract passengers, cargo etc, will lower that further.

 

I must of measured that wrong then, cause it came out to 145. But I have the 18's which is on page 251 and it shows 8800. with the 3.73. Can I just like call up ford and tell them my VIN number and they can tell me? This book is driving me nuts.

 

I was looking at the 2604SS from Rockwood RVs.. But I cant find the weight.

If you have the 18" wheels, you have the 3.73 rear.

Assuming you have the right options, that gives a GCWR of 14,500. My other numbers still stand, truck is at least 5500 empty. You will need to weigh it to be sure. Add in everything you are going to carry to get the true available tow weight.
As for the trailer, they just haven't announced the weights yet. Being a 26' ultralight, you should be okay. Just make sure of the numbers before you buy, and don't trust the sellers as to what you can or can't tow. They would tell you you could tow a 30' fifth wheel with your truck.
You should still get a weight distribution hitch with sway control. Those will help quite a bit in high winds and passing trucks.

 

Yeah, my parents just got ride of their tow behind for a 5th wheel and he kept all the hitch, sway control and the weight bars.and he said he"d give me his stuff seeing how he doesn't use it. His stuff pulled a 13000 pound trailer with no problems. So it"ll do just fine for me. :-)

 

Honestly, towing 8k pounds or more should not even be a discussion for a 1/2 ton. The truck would be over GVWR.

Anyway, download the brochure as it gives the specs. GVWR of the trailer is about 6600 pounds, perfect limit for a 1/2 ton such as yours.

With 145" wheelbase, are you sure you have a Screw and not the Scab? 4 full sizes doors instead of the rear suicide doors?

I know what I have. LOL......

 

So, what do you have? That 145 foot wheelbase must be a bear to turn around.

Only 139" and 150" wheelbases were available in 2008 on the Supercrew (5.5 and 6.5 foot beds respectively). Which way did you err? Five inches shorter (150"), or six inches longer (139")?

Other bed lengths are:
126" Regular Cab (6.5 foot box)
133" Super Cab (5.5 foot box)
145" Super Cab (6.5 foot box) Regular Cab (6.5 foot box)
163" Super Cab (8 foot box)

 

lol, I was out there doing it myself cause no one wanted to go out in 20F weather to help me. But it was closer to 150 so I prolly just didnt have the tape in the right place.

 

How would the truck be over GVWR at 8k pounds?

 

GVWR Maximum 7200
