Well I don't support the Walton family and my truck runs 10,000 miles on a full tank of DEF. If your truck is using that much DEF you might want to have it looked at.
Point being it's a heck of a lot easier to pull up to a pump, swipe your card, put the nozzle in, pull the handle and let it fill. Or hold two boxes hoping the tube doesn't pop out and spill all over the side of your truck, whatever works for you and makes you warm and fuzzy.

BTW that 10,000 miles includes towing a 6000#+ boat to the lake Eire 40 to 60 miles round trip two to three times a week May through October.
As far as how much DEF my truck uses it's right on what the book says.
If your 6000 lb boat is putting an appreciable load on your diesel truck that would impact your DEF usage then you need your truck checked.
If you're getting 10,000 miles with a tank of DEF then you're saving about 1/2 what I figured. In about 100,000 miles you're saving about $25.
