That is why vehicles are given ratings in the 1st place. You don't see "regional exceptions" on ratings.
That's exactly the problem I was trying to lay out, Wayne. In my opinion, there SHOULD be regional exceptions (or at least regional advisories) on tow vehicle tow ratings. It doesn't take much thought to realize to realize that a single one-size-fits-all number cannot possibly cover all situations. But that is what the manufacturers give you. Again in my opinion, the tow vehicle manufacturers quote the best possible number (that is, the sea-level flatland number) because it maximizes their chance of selling you a vehicle. It is up to the buyer to realize that the flatland number won't apply when you are not in the flatlands.

I can guarantee you that a 3500-pound rated vehicle will not be adequate going up 8% grades at 8,000 feet as you approach a campground in Yosemite National Park in the high Sierras - or a campground at 10,000 feet in Colorado. I have gone both places with my TM and Explorer (rated 6800 pounds), and it was a long slow slog. [Full disclosure - I am unwilling to run the engine near red line for prolonged periods of time.] In spite of the fact that I had more than 2-to-1 margin (according to Ford), there were moments when I wasn't sure I was going to make it. Again in my opinion, there should be a regional advisiory, but since there is not, it is up to the owner to be smart about it.
