In today’s American Truck Simulator video, I turn the legendary Peterbilt 389 into a full heavy haul beast! From performance upgrades to custom parts, this build is designed to pull some of the biggest and heaviest loads in ATS. If you love heavy haul rigs, Peterbilt builds, or ATS customization, this video is for you.
