How much DEF are you using. Have read some horror stories on other forums.
Trying to help me make a buying decision?

With my 2019 I've been using more than I did with my 2011 truck. The 19 has been averaging 4,500 miles to the 7 gallon tank and the 2011 truck was getting 6,500 miles to the 5 gallon tank. Doing the same type of driving and pulling about the same number of miles with each truck. I just had my truck at the dealer this week for the recall that was to fix the excess DEF usage so I'll see over the next few months.

I have a 2020 LM2 3.0 Dmax.

Only have 900 miles on it but DEF showing full.

Dealer topped it off before when I purchased it.
