Also don't know how to do pics but when ford still used steel bodies 2014 and earlier they had a GVWR of 7700 for my configuration (157 wheelbase and max trailer tow package).
So from what I understand, unless ford made the axles, brakes, tires, and frame etc.... weaker the gvwr should be the same if the body is lighter. Every year they tout and avertise the frames and axles are stronger not weaker.
So my GVWR is stickered at 7050 and it used to be 7700 does that mean I can theoretically haul an extra 650 pounds?
Why make body lighter and lower GVWR at the same time? Sounds counter productive.
Cant post pics but here's the link. Page 4
