Conspiracy theory. Internet social media nonsense. You won't find any chassis engineers that agree with you. The Ford engineers reduced the GAWR on the 2015 because the lighter weight aluminum body didn't require as much GAWR to accomplish similar weight capacities for hauling weight as the previous F-150 steel bodies required. One of the reasons for converting to the aluminum body was to save weight, which results in improved MPG. So yeah, a 2015 should get a bit better MPG than a comparably-equipped 2014, but that's not because of any conspiracy theory. GAWR is not just the weight capacity of the axle shafts, but the entire package of components required to carry the weight on that end of the truck. Axle shafts, but also bearings, differential, suspension, tires, wheels, etc. Some of those components can be made lighter weight if the weight of the body is reduced 700 pounds.

That's because Canada changed its testing system in 2015.
Manufacturers are using an improved testing procedure, introduced for model year 2015, to determine the fuel consumption ratings of new light-duty vehicles. The Government of Canada-approved 5-cycle testing better approximates typical driving conditions and styles, resulting in fuel consumption ratings that are more representative of a vehicle’s on-road fuel consumption.
The 5-cycle testing procedure supplements the standard (2-cycle) city and highway tests by integrating three additional test cycles that account for air conditioner use, cold temperature operation and driving at higher speeds with more rapid acceleration and braking. For the same make and model, 5-cycle testing produces fuel consumption ratings that are 10 to 20 percent higher than 2-cycle ratings.

Thanks brulaz. I was already aware. The EPA also used the same and before Canada. The stickers changed in the USA as well. Anyhow I've discussed this to death. There have been many investigative reports here in Canada on this so I was not surprised. At the end of the day I really don't care I have a new 2016. I bought it regardless of MPG was just surprised that I couldn't get a 3.73 with EB unless with HD. This is when I did some further digging. Was only trying to see if anyone else had similar conclusions. They don't and that's OK......old topic for me know. Thanks again Brulaz.

Maybe I missed it as I scanned through pretty quickly. I believe the new trucks are rated using SAE J2807 for tow capacity while the previous generation were not.
I know a 2011 5.0 SCREW w/3.55's had a tow rating of 7,700 while the same truck with 3.73's had a tow rating of 9,300. A 2015 5.0 SCREW w/3.55's has a tow rating of 9,100.
