J2807 does not mean the weights are anymore accurate than non J2807 ratings. Read the note #1 in that guide. The weights are estimated!!!
"1. Payload and Max Trailer Weights are ESTIMATED values."
Don't worry in 2017 Ford will be able to use those same "ESTIMATED values"
Not worried at all. Ratings whether SAE or not, they are estimated. You should have stated "Ford Super Duty 250/350". The '16 F150/450 uses the standard and the majority of other Ford vehicles use it as well.
Now if all the big 3 could get on board using the same standard for measuring engine output.
