I have a Sportsmobile EB Ford with their Penthouse roof and the 4.9L I6 with a c6 and 3.08 gears. I get 18 hwy mpg when being careful. I think one of these with a 4bt Cummins could do 25mpg easily and with OD and tuning, perhaps 30.

I currently have zero aeromods and zero mechanical mods installed. Totally stock.
