With the HiLo, we got average 15 mpg even through Virginia when we traveled Back East.
Now, it's about 10 or 11.
Just checked my spreadsheet for Florence, AZ to Buffalo, WY
Show Low, AZ 12.3 to Gallup, NM through Salt River Canyon
some 11s and 12s then 16.1 from Las Vegas, NM to Walsenburg, CO
Then back down to 10s
Then a big 14 from Cheyenne to Douglas, WY
Gallup, NM to Snowflake, AZ down to 9.8 which would be through Salt River Canyon where they had construction neat the top coming back out on the way home.
According to the spreadsheet, the average was 12.1855 mpg.
Not quite as bad as I thought, though.
