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?

I have a 2013 Silverado 3500. I was told to expect 5000miles on the 5gal DEF tank. I filled it with ~3.5gal at about 4000miles, and added another 4gal when it said I had <1000mi left around 7K on the odometer. I'm currently at 10,000. I think I'm getting around the 1000mi/gal as advertised, maybe slightly better.
