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?

Have a 2014 Dodge 2500 Cummins 6.7L, 32' 5th Wheel, towed several times this summer. It's a huge improvement over my 01 Chev 2500 6.0L but still only averaging about 12.5 MPG
