Just got home; 2050.8 miles, 69.2 gallons, 29.6mpg.
First 350 miles were 80ish mph
Next 400 was 67-68mph
Then 100 miles @ 40-50mph on snowy roads.
250 in town/to from Rocky mountain national park/ etc etc
Remaining miles 73mph driving home.
I should also add, the trip computer I had set for this trip reported 29.7mpg, so between my 2.9% odometer correction and the 3% adjustment I had the dealer make, I'm pretty much reporting correct mpg
