I cold never maintain 70 mph up a 6% grade with the old diesel nor the 2012 6.2 Ford.
What were you pulling? I don't think I've ever shifted below direct gear on any grade at highway speed, and I have never been unable to maintain 70 mph.
Come to Colorado.
I'm in Colorado several times a year and I live in New Mexico. By the way, the steepest highway grades are in Utah, not Colorado, and I've driven all of those, too.
You must have been pulling something seriously heavy if you couldn't maintain 70 mph in a modern diesel truck.
Somewhere I got in my head that the weight in question was 12,000 pounds. Which you will not pull at 70 MPH up either Eisenhower or Vail pass. I would still question 70 MPH with 8000 pounds over either of those passes, but it is plausible with the new diesels.
