2017 GMC/Chevy DEF tank!

$65,000.00 one ton dually. I have no plans to take it off road. That's why they make Jeeps. Hasn't been a problem in any way in the two years I've owned the truck. I like the fact that the DEF is under the hood. When is the last time you heard of someone pouring DEF into the fuel tank on a GM product? It's not like you have to add DEF every week..
