I have a 2016 Ram 3500. We just got home from a 3000 mile trip. I filled my DEF prior to leaving and when we got home it was in the red. I did have a camper and horse trailer. Is this consumption normal. Seems excessive. When I took my truck in for a recall notice before this trip I asked the tech about the DEF consumption my truck was having. He said he did a software check and update but this thing is really going through the DEF.

 

Welcome to the diesel world! That sounds about right. There how much my diesel consumed before I traded it in on a 2500 Hemi
