2022 Freightliner Summit Hauler M2 106 Vs a M2 112 Hauler

What is the difference between the running gear besides the engine & transmission? Are the axles the same?, brakes the same?, frame size...?

What’s the mileage difference between Cummins and Detroit?

There's not much of a difference between them. But pulling loads you will see that difference because the 112 can pull more than the 106
