So, actually, I think Andre read this wrong. It does not say reduce your trailer by 2% per 1000' it says reduce your GCW by 2% per 1000'. So on a truck with a 17000 lb GCWR, you should really only be at a GCW of 13600 at 10000'. So its 3400 lbs reduced or a 7600 lbs trailer.So for you fellas with pre-2021 trucks, does your owners manual specifically state to reduce your towing capacity rating on the truck by 2% for every 1000' in elevation?
It appears that my 2021 does state that and that would require me to reduce my ~11000 lbs by at least 20% when I head to Colorado. That would be around 8800lbs.
Ford also claims that they are the only manufacturer that notifies the driver that the truck is in reduced power mode. (limp mode is what we call it)
And get this, according to Ford, the towing claims and cooling capacity is based on an SAE standard (SAE J2807) that is done at 45mph. I couldn't find any specific mph mentioned, but the articles did state that there was a MINIMUM speed) This was all news to me and I wonder if this thread would even exist if we were towing with the reduced GVWR based on elevation AND we never exceeded 45mph on these grades that are known to be our nemesis?

I got this info from Fords response to TFL F150 going into "Rduced Power Mode" towing 10,000 up Veil gauntlet. (10 mile climb)

That of course is the maximum assuming your truck isnt loaded up with gear.
