2022 Yukon Denali 6.2: beat my all-time high MPG!

[vcode]

I have a real hard time believing these figures as many here a happy to get 20 mpg with the 6.2. Is any of this backed up with real data, like miles and gas pumped?

28.3 mpg Las Vegas to SoCal, 2018 Tahoe Premier RST 6.2L 10-speed trans, all the details in this thread..

28.3 MPG on a recent trip in my 2018 Tahoe RST 6.2L 4x4

On a recent solo trip from Vegas to Rancho Cucamonga I got over 28mpg over a 214 mile trip. I snapped the below photo as I was exiting the highway. I had the cruise set to 74mph most of the way, until I got on the Cajon pass, then set to 68 coming down the mountain to allow the engine braking in...

There's a lot of variation in 6.2L equipped Tahoes/Yukons/Escalades. Mine is the 2018 Tahoe Premier RST has the L86 4x4 with the 10-Speed trans and has V8 and V4 mode. Escalades and Danali's with the same powertrain are heavier, the 2021-22 of all varieties are even heavier, but have multiple cylinder deactivation capabilities. I average 22-24 real MPG on highway trips between SoCal(LA Area) and Arizona or Las Vegas cruising with traffic around 80mph with a load 2-3 adult passengers and about 200 pounds of gear, 15 MPG around town, with a heavy foot. My 2015 Tahoe 5.3L with 6-speed trans got about 1-2 mpg less, same load, same routes, same speeds.
