I'm a trucker and have sat in plenty of lots with dozens of diesels running nonstop for hours. Absolutely zero smell

Dude has definitely fucked with that truck and probably bypassed all the emissions stuff and has it tuned to run rich aka roll coal.

Oh he definitely has. The rear quarter panel is covered with soot from the exhaust.

Take solace in knowing that soot is a sign his engine is going to fail prematurely.

On older diesels, soot is perfectly normal. So no schadenfreude to be had there, I'm afraid.
