The 10 speed with lower combined load should have stomped the measly 6 speed with 6 tires dragging the road.

Same downhill braking. GM should have been better with lighter load and higher revving engine to give more braking HP.

Heavier combined load but better economy.

How many here still think the “BRANDED” 10 speed is the Savior???

The extra 100 foot/pounds in the RAM certainly didn't carry the day. Your trusting the DIC to decide who has better fuel economy when they are separated by tenths of a gallon? Certainly you know better.
