Got a 2014 Ram cargo minivan. I have 82k miles on it. 25 highway at 75+ is a bit low. Going to El Paso, a 7 hour drive, I usually get 27 mpg most of it at 80 mph. Mind you I have no interior to speak of in the back, but I probably have 3000lbs of tools/parts/fat assed driver in it.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
