Just getting back to this...
So I never ended up taking my truck to the dealer. Before my appointment, I started noticing this smell in other places outside of my truck, particularly when there was a breeze on my face, much like vents pointing at you in a vehicle. I google why do I smell something no one else smells and it returned pantom smells. This can be caused by a whole host of things. For me it was just sinus pressure due to allergies, according to my ENT. After a course of steroids, no more smell. Crazy!
