I was impressed with the first short trip I made with mine.
Wow! That is great MPG. I saw 24 mpg in mine on our first 200 mile trip across the SoCal desert, some grades, but it was during the breaking period, so I kept the speed down. Since then, we average 18.5mpg with a load of about 800 lbs. City seems to average about 15mpg. Towing is about 10-12 with a 7,500 lb load.
I'm sure the extra torque of the 6.2 in your Denali helps your mpg more than the EPA estimate gives credit, when you're not romping the throttle.
