DEF tank will go every 3k or so miles, so stay on top of that. 
 
EFIlive, remove all torque limiting so you can actually tow with those big numbers

 Yea they said 3 to 5k range. I heard going to a place with big trucks will have fresh DEF on pump so that will be my project for this week. I can feel the truck is softer in 1st on purpose to limit torque so I'm sure the computer is pulling things back.
