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...

That would be about normal. My 2013 used one box that you can pick up at Home Depot for a good price to go about that far. When you reach 1/2 tank, one box to fill it. $12 is not that bad.
