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.

altitude is a killer

my 8.1L 'burb barely made it over Monarch with the 9600lb TT

hoping the turbo on our 7.3L PSD fares better

Ford has had much of this power loss altitude information on their towing web pages. Ford has even gone so far as to provide towing reductions for frontal area of the fifth wheel or travel trailer. They do a nice job on their towing guidelines.

I have to laugh how they relate a performance issue back to safety.

The same automaker that calculates payload ratings without items few trucks actually have such as bumpers or center consoles?

and then the article authors don't even know how to read and follow directions.

I find it disheartening that in today's society that there are people that will sue over the drop of a hat. For this reason Ford has to put this in writing. We see it a lot on these forums too. Lawsuit, lawsuit, lawsuit. People like this just make hard things harder. Safety rules in the work place has also gotten out of hand because of people suing over anything and everything.

Already another thread going on with this story.
