Tim, i have driven a big truck since 2009 and back when the big trucks started to go to the DEF because of BIG GOV, we would have to go into the truck stop and buy the box of def and it was $$. i have watched a lot of your videos on your diesel and you and others would go to wal mart to buy the def. my question is this 2 parts 1, did you fill up your truck at a truck stop and use the def at the pump that cost around $2.99 a gallon. or 2, buy at the gas station and go inside to buy the def? im still up in the air but leaning hard towards the AT4 diesel and alwasy thought i would keep filling up at the truck stop and use the def at the pump and save big time in the cost of DEF
have a great day
