Tow rating decreased for altitude

Ford says reduce GCVWR by 2%/1000 ft. then the authors talk about the effect and says well, at 10,000 ft the GVWR of the truck goes down to only allow about 400lbs of cargo. I call BS. the ford document says reduce GCVWR, NOT repeat NOT GVWR. it affects the towing capacity, only.

Um... One affects the other so in essence it is a correct statement.

Ah no. In this case, GCWR is a performance limitation, GVWR is a structural limitation, that is why Ford doesn't mention GVWR. Your truck structure and components don't get weaker at higher altitudes, only its performance is reduced.

The authors of the article don't seem to know the difference.
