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?

As a Duramax owner, I can say I would have been delighted with 12-13 towing our fiver. :) I bet any honest PSD owner would say the same.
