I just got a 2011 f150 a few weeks ago with the ecoboost and 3.73 rear end. Was curious to know if I have max tow package though. I have done research online and looked up the vin and can't find anything that will tell me. Is there anything specific I can look for to know for sure it has the max tow package?

 

If you have the big towing mirrors that should let you know. There is a code in the vin that will tell you. Somewhere on the fourm here is a vin-decoder. Plug your vin into it and it will tell you everything about your truck.

 

We'll I don't have trailer mirrors but I do have the transmission cooler and trailer brake controller

 

There are two trailer upgrade packages.

The first one has all of that.

The second one is the max tow with all of that with the larger tow mirrors and a upgraded rear bumper and recover hitch. So by the sounds of things, you do not have max tow. Just the standard towing package.

 

But not to worry because the differences between the two,two packages are generally insignificant.

 

Not true. The max tow package gives you a higher payload and tow rating over the standard towing package.

 

Max tow should have 7 lug wheels...

 

Max Tow DOES NOT have the 7 lug wheels...The HD PAYLOAD package does.

 

...and the "upgraded" rear bumper is just like the "regular" rear bumper. So in the bumper department you really aren't missing anything.

 

The regular tow package lays all the foundation for towing including; hitch receiver, 4-7 pin wiring, engine & transmission coolers, etc.

The max-tow option extends upon the regular tow package and adds the rear bumper upgrades (additional hitch support), towing mirrors, stiffer rear springs, 3.73 and up gearing w/e-locker, and integrated brake trailer controller. This bumps the GVWR up as well. Both the trailer brake controller and gearing selections can be optionally added on the regular tow package.

Finally the HD tow option extends upon the above two by adding 7-lug hubs/wheels, even stiffer springs (all the way around), stiffer shocks, different wheels, and LT tires. There are some configuration nuances with this package between the Eco and 5.0 platforms. On the Eco you require the max-tow in order to select the HD package, whereas on the 5.0 you can build the HD package directly from the regular tow package. The HD package maxes out the GVWR and RGAWR
