Anyway.
At this point the economy isn’t “bad” comparatively on any of these trucks (if you look back 10 years anyway)
That said my 6.2 suburban could turn 28mpg with a 5 speed stick, and it was cheap and didn’t require a turbo (which tends to plug up in cold climates)

Road and Track got 43mpg with this truck keeping it under 60 mph. Being able to get 28mpg and getting a modern EPA rating of 33mpg are two very different things. This truck really puts to shame any full size ever made before and the Ram is supposed to be even better. Wasn't that long ago an epa rating under the current standards would be less than 1/2 what this gets. That's like a Malibu going from 35 mpg to 70 mpg epa rated in 10 years time.
