I took delivery of my '15 ED couple days ago. I was in a rush to go to school, so I didn't have much time to take a look at everything. One thing for sure, DEF was almost empty and the salesman only gave me a gallon of DEF. I Called today and he said that management verified that I only get a gallon. It's like saying, I have to buy the rest of my engine oil because it's half full or brake fluid on a brand new truck. I told them to look into TSB 25-006-13. I also emailed and chatted with RAM support. They'll give me an answer tomorrow. Anyone else paid for theirs?
