Note: For high altitude operation, reduce the gross combined weight by 2% per 1,000 ft (300 m) starting at the 1,000 ft (300 m) elevation point.

So you could be within all weight specks and still be over weights at times like on I 80 in Wyoming at 8800 feet. There you would be down by over 17%.

All the more reason to have more towing capacity than you need.
