DEF mileage on 2013 2500 4x4 4dr

[Powder Extreme]

My son was just commenting today on the fact that his new 13 DRW Aisin uses pretty much the exact same amount of DEF as the 11 Denali DRW he traded in.

Interesting, thats an apples to apples comparison of mine. How many miles on his 13?
Hopefully I can get mine reflashed today or tomorrow, heading out Wednesday or Thursday for 2,000 miles towing.

He has about 4k miles on it. 1st 1000 empty then some 10000 lb loads and acouple hundre with 16K
It is starting to loosen up now noticeably. In man 5th it will make tires squeak at 65 if you get on it.
Very strong engine 100% stock
