I don't think it's possible to make economical at any scale other than to become a product facility and have a retail market. That being said, if you're a prepper and want to keep the truck on the road after the zombies come, you can get RODI systems fairly cheap. I have one in my basement I use to make all the water for my salt water aquariums. Filters are pretty cheap for the gallons they can process. You WILL void your warranty though. So it's a horrible idea.

I do not believe an EMP would effect the fishes given the density of water. Climate change or floods might be a bigger concern for him.

I'd look for the closest major truck stop. Since you only need it every 5k it's worth the trip. Buy it at the pump.

I stopped buying DEF in the Jugs a year or so ago. I pull into one of my local fuel stops and pump DEF from the Pump. In particular there is a new Maverik C-Store close to me that has DEF at the pump, No magnet needed. Seems to be designed to sell DEF to pickup truck owners. But most of the truck stop type fuel stations have DEF at the pump, but they seem to need a magnet for the flow control. And most will loan you the Magnetic Ring if I just walk inside and ask to borrow one.
Since I can pump exactly what I need to top off the tank. I usually fill up the DEF while I'm getting diesel and I see it's below half full. Sometimes that's 1 gallon, Sometimes its 4 gallons, Depending on how long between fill ups and how much towing I've done.

Walmart $7.88 for 2.5 gal = $3.15 a gal
But seriously, even at $10 a gallon it's not a real factor in the operating cost of running a diesel.

That stuff is expensive and all DEF is according to wikipedia is urea and deionized water!
I saw this: Urea, 50 lb Bags [ureabags] | DudaDiesel Biodiesel Supplies
And I can get bulk deionized water at a local shop.
Anyone tried mixing it themselves? I think I'd just mix it in my 5 gallon jug I use for dirtbiking!

The old saying is if you have to ask what the Mpg's are..then don't buy it because you can't afford it. Same concept.

I found this about mixing your own DEF:
http://www.trucknews.com/features/dealing-with-dpfs-and-def/
"""
The other potential mistake – which seems unthinkable but actually became problematic in Europe where SCR has been used for years – is the use of home brew DEF.
“In Europe, some guys thought they could make their own stuff,” de Sousa said. “They got a buildup of residue with non-API certified DEF. You get deposits and the catalyst is useless and you’re basically looking at a replacement cost of about $6,200 each.”
