My target speed is 63mph, give or take traffic fluctuations. I run towyrhaul and lock out 10th gear. The truck rarely finds 9th unless I hit 65mph.

We did a 1500 mile round trip from FL to the Smokies last summer. Averaged around 11MPG on the on board, so 10 real world. Mine is historically 1MPG off.
More recently we did two trips withn FL, so limited terrain. Averaged 11.9 on one and 12.9 on the other according to the onboard. So about 1MPG less real world.

I just got 6 MPG, hand calculated, on my way back from Galveston yesterday running 60-65 MPH . That was with 17 MPH head winds which sucked. My trailer is 24', 5700# dry, so around 6500# loaded with my 2017 3.5EB max tow Platinum. I have never had issues passing 18 wheelers until yesterday. had 1 scary moment when I passed a wide load trailer. Just as I passed him, the truck/trailer verred to the right sharply right in front of the 18 wheeler. I just got sucked in by the draft I am assuming. Never had that before.
