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?

The reason the inside of the exhaust is clean and you don't get the typical diesel exhaust smell is due to the DPF trapping soot particles, not DEF.
