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?

55mph would improve mpg substantially but not sure about 18mpg. I get 11 towing at 65-70. At 55mph I can get 14-16mpg but thats with A/C on. Maybe a bit more with A/C off but haven't measured that.
