DEF refill
I have 5400 miles on the 2013 Ram 3500 and its time to refill the DEF tank. Mostly easy driving and minimal towing so far. How many miles are you guys getting on a tank?

1000 mpg seems to be the norm in mixed use. If you tow heavy, I've heard it dropping down to 500 mpg for the hard core towing guys.
