DEF - Usage
Just on my maiden voyage with my 2014 Ram 3500 Diesel pulling 13,500lb 2009 Cardinal 34'. Pulls like a dream very nice to drive however after 1,000 miles I have gone through 1/2 tank of def, 2.5 gals...

2015 3500 I'm getting a bit over 4,000 miles per 2 1/2 gallons of DEF. So far this has been consistent for about 28,000 miles.
