Mileage for a Yukon XL Denali?

[kushog]

I am picking up my 2016 6.2l Yukon XL Denali today. I was just wondering what kind of mileage is everyone getting with the 6.2l. I am trading in my 2015 with the 5.3l, which was averaging about 19.5 - 20 mpg on the highway.

I have averaged 18.0 mpg in 7700 miles in my AWD 'regular' Denali. About 75% highway.
