DEF question
Hey I am still in my learning phase of about diesels to see if I want one for my next truck let alone need one. I am here in SLC I currently drive a company vehicle. I see where DEF goes bad in 100+...

Unless you don't drive your truck much you will need to fill up your DEF every 7,500 miles or so. Less if you are towing. I wouldn't stockpile a supply, but I wouldn't worry about it going bad in the truck.
The bigger issue is sometimes finding it when you really need it. Last year towing in the West I had to break down and buy some at a NAPA. Normally I try to get it at a truck stop in the big boy pumps they have it at the pump for a much nicer price.
