2017 GMC/Chevy DEF tank!

If a company is willing to let something distracting as this works its way into a production model, who knows what other engineering compromises they made behind the sheet metal that we can't see. It really doesn't matter whether it's a legitimate ground clearance issue or not. If a certain percentage of consumers perceive it as a "flaw", or just plain ugly, at a minimum they're going to lose some sales over it. It's hard to believe the engineering team at GM couldn't have done a better job of hiding that DEF tank. It's just a big ole wart on an otherwise fine looking truck.
