18 mpg Dodge while towing?
Friend claims 18 mpg while towing 35' toy hauler with 2003 Dodge Cummins Diesel with manual transmission. He says he never goes over 55 mph. Is he for real?

Not unless his tow hauler is light-weight and has no frontal area. I get 12-13 depending on terrain. Unloaded I get 23-24. Yes that is hand calculated.
