One possible meaning of the "-" in the 2017 guide you link to is the 4X2, 2.7, 3.55, CC combo was not offered as an option in 2017. Otherwise the dashes don't make much sense. Think about it, look at the Table, a given configuration at XX,XXX GCWR can tow Y,YYY pounds but the same configuration at a GCWR of XX,XXX + 100 has a "-". Does this mean it is not recommended to tow anything? I suspect it means that combination was not offered that year.
I think a more probable interpretation is the combination of an F150, 4X2, CC, 2.7, 3.55 was not offered in 2017 hence the "-". In 2018 it was offered hence the 7700.
I beleive this is correct as well, since the 4x2 2.7 powered F150 with the 3.15 or 3.31 axle ratio is rated at 7600 towing/12,300 GCWR. It stands to reason that if 3.55 gears were available in the 4x2, it would be rated to tow more than the 3.15/3.31 rather than not rated to tow at all.
