Maybe each truck differs enough in that respect to have similar limits in their remaining available total?
Likewise, the larger truck blocks more of the trailer with its body so by default a larger truck can tow a larger trailer (with regard to frontal area) than can a smaller truck with the same frontal area limit.

The size of the truck doesn't factor into the frontal aera, unless the truck itself is bigger then the trailer in some dimensions. It's not the difference in frontal aera or the added frontal aera but the overall frontal aera. It's just a bad move by Ford you don't get with Dodge or GM, I have a feeling they would drop it if it were more widely known. Almost every modern travel trailer on the lot is more then 60 Sq ft frontal aera which means the only 100% acceptable tow vehicle produced by Ford is a f-550 with Max tow package. I agree there are other things to consider but I get blasted on any towing forum when I point those same arguments out as applied to the other numbers listed in the tow guides. Those numbers are also worst case scenario and will vary with other factors.
