I have a 2010 f150 with a 5.4L Triton engine, 3.73 rear axle ratio, auxiliary transmission cooler, integrated trailer brake controller, and 36 gallon fuel tank. It has a GVWR of 7675lb. I don't know the GCWR. I need to determine if this truck has max tow package as I pull a 7600lb trailer. With max tow package the trailer tow rating is 11,200lb. How do I determine if this truck has max tow package for sure or not? I've tried VIN decoders to no avail.

 

Search around for threads where people are requesting their window sticker. Max tow is not called max tow on the sticker, there is a thread on that as well somewhere.

 

Whether your F-150 has the max tow pkg or not will not tell you anything you need to know about towing. That pkg is mis-named. It does not result in max tow unless combined with the heavy duty payload pkg (HDPP). With GVWR of 7,675, you do not have HDPP. 2010 HDPP was GVWR of 8,200 pounds,

But a bit of snooping tells me you do have the max tow pkg. The 2010 Ford RV and trailer towing guide says with 5.4L engine and 3.73 axle ratio, but without HDPP, the Harley Davidson trim pkg, or the FX4 pkg, then all remaining configurations of F-150 with 5.4L engine and 3.73 axle ratio have max tow. GCWR is 17,000 or 17,100 and tow rating is over 11,000.

But ignore that 11,000 tow rating. It's not your limiter as to max trailer weight you can tow without being overloaded. GVWR, or payload capacity available for hitch weight , is your limiter. So weigh the wet and loaded F-150, then do the math to see if you can tow a 7,600 pound TT without bein overloaded. But with GVWR of 7675, I'll bet you're not overloaded with a 7,600-pound trailer.

 

Thanks for the insight. Ford needs to be more transparent on this important issue. I went to my local dealer yesterday and they pulled up the original window sticker for me. On line window sticker queries don't work unless the vehicle is posted for sale or you are a dealership. Because I purchased this truck as CPO, I never had the window sticker - now I do. My f150 does have the Max Tow Package listed on the sticker. Using the 2010 Ford towing guide my max trailer towing is 11,200#. You are absolutely correct that any added weight in the truck or the trailer reduces this value and must be accounted for. Ford should make the GCWR of their trucks easily known just as it does with the GVWR. That would make this whole problem go away.

 

If you want Ford to force independent dealerships to detail towing restrictions, not going to happen.

All you need to know is detailed in the Towing Guide. Here's some screen shots from my 2015's TG:





They also list proper camper loading:

 

All well and good, except that to find the correct row you must know the truck's GCWR. Only the GCWR is labeled in the truck, not GCWR. Frustrating.

 

What is the cab style and bed length? Is it a 2wd or 4wd? FX4?

With enough information you can usually narrow it down.

 

You don't need to know either GVWR or GCWR. In the guide, there is a single line for each engine/axle ratio that you cross reference against your cab/chassis length/driveline. Once you've identified your truck, you've got your GCWR and trailer weight rating.

Here's my truck in the chart below. I've removed other engine types to reduce the chart size. 3.5 eco with a 3.31 axle is the rows I boxed in red. My super crew, 4x4, 5.5' box is the column I boxed in blue. I have only one trailer weight listed because payload package and Max Tow are not available with the 3.31 axle. For the axle ratio/engine combinations that have payload package and Max Tow available, you will have more than one max trailer weight listed in your column, in which case you need to know if you have those or not. Follow the line with your max trailer weight rating (green box) back to the GCWR's listed for your axle ratio, there's your GCWR (also green box).

 

 

Not really as simple as that. Here is the 2010 F150 towing guide. For my 3.73 axle, and my short bed 4x4 supercrew, two numbers are indicated. For the 11,200# tow capacity to apply, footnote (4) says "Max tow package required"
