My wife and I just got back from a 1500 mile trip from Idaho to Montana and back. I have a 2017 4X4 F150 with the 5.0 and 6 speed transmission. We live at an altitude of 2520 and the trip started here and went all the way to over 7000 feet when crossing the Continental Divide a couple of times. Our trip consisted of a combination of freeway driving at 80 mph and two lane mountain roads where the speed limit was 25 mph at times on numerous curves.
I was very impressed with the power my 5.0 maintained at these high altitudes. I did not feel at any time a lack of power or response of my 5.0 engine even when climbing mountain roads at over a 6-7% grade at these high altitudes. The 5.0 performed perfectly as well as the 6 speed transmission. We also averaged 20.1 mpg over the 1500 miles. Great trip and a great truck.
Just keep in mind that the yellow signs on corners are advisory, not regulatory--they're suggestions, not speed limits. On dry pavement, most of the ones around here are at least 10 MPH below a comfortable pace in my F-150, and the differential only increases on two wheels. The actual speed limit from just south of Red Lodge to the Wyoming line on the Beartooth Pass is 70 the whole way, for example. I'd love to see someone pull that off, but I don't think I'd want to be in the car while they were trying.

Wow! Is that system reported mpg, or calculated gallons/miles? I'm curious because my '16 Screw with the same engine, 3.53 dif. has varied (actual - not system) between 16.1 and 21.2, with the latter over flat terrain and under 70mph.
Did you add the Borla Touring Exhaust yourself? Was there a noticeable difference (and where in the power-band)?
My 2017 is a 3.31 rear end and yes I added the Borla Touring exhaust myself, very easy install. The MPG was hand calculated over the 1500 mile trip. The vehicle MPG calculation was actually pretty close and only off by a couple of tenths.

7000 feet, you jest. To get to 7K I'd have to drive 30-miles - downhill. When I cross the Continental Divide closest to me it's over 12,000 feet. Was up there few days ago for a hike, all uphill.

When my truck is parked in the garage its sitting at 7,800ft. Still, I appreciate the OP' post with a 1,500 mile trip and 5,000ft vertical climbs/descent thats pretty good gas milage!

Flatlander!
How'd you manage to hike all uphill and still get back to the trailhead? That sounds like the way my parents walked to school.
