The reason people are obsessed with "rolling coal", I have no idea. In reality, it means you can dump more fuel into you engine than it can burn. Not sure how that's impressive.
People see an older tractor trailer climbing a hill with a heavy load and belching sooty exhaust and they think:
Sooty exhaust=Power.
So they tinker with their engine to make sooty exhaust, so they can look "powerfull".
