Wow, this shows absolutely no understanding of how ERA works. Let's pretend for a second that the light steel in a truck is enough to protect against the backfire of an ERA brick. It's not, but let's pretend. Even then, only the door would be protected, everything else that's on glass, which all of it pretty much is would backfire into the truck cabin. It's like sticking grenades all over your truck.
Uh, idk about the side panels of that truck, but that glass sure as shit isn’t strong enough to handle the ERA going off. That’s a death sentence for anyone in the cabin.
