tow/haul mode
I have traded my 08 6.4 for a 2013 6.7 powerstroke and love it, going thru the on screen displays and truck apps, it had tow/haul mode. it described what it did and at the end said when traveling on level ground tow/haul mode is not required and can have better fuel economy. my question is do you use tow/haul mode no matter what or just when needed going thru mountains etc... I have always used it on my 08. and didn't give it a thought until I read it on the monitor on the truck .... thanks for the reply,
