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...

Way cheaper to buy anywhere else but the dealer. Walmart, truck stops etc. If you are pulling a load you will not get the mileage otherwise. But it wouldn't hurt to have the truck checked out.
