The Peterbilt 579 UltraLoft is one of the most sophisticated semi trucks ever built. Semi-trucks carry BILLIONS of dollars worth of goods, being driven across BILLIONS of miles of highways. Close to 70% of goods being delivered to your door were at one point being pulled by a semi. That’s a lot of money and a lot of responsibility on the truck AND the driver. But this show isn’t called H2B (hat 2 boots), so sorry Dale, we can’t teach the kids about your Steston and your Tony Lamas. But what we can do is dive into one of the biggest, smartest, most tech heavy semi trucks ever to hit the road - the Peterbilt 579 UltraLoft.
