Rezbilt 389 (modified Peterbilt 389) for American Truck Simulator

What this mod does

The Rezbilt 389 is the SCS Peterbilt 389 modified by Allen Rezbilt. It has more than 185,000 subscribers on Steam Workshop and is one of the most popular modded trucks in American Truck Simulator.

What it is

The author starts from the in-game Peterbilt 389 and adds his own parts. According to the description, all the modified parts were created in Blender and none were taken from other trucks. Many were modeled after in-game trucks and real trucks.

Compatibility with other mods

Other popular mods support it. Interior Cabin Lights by Eddie Yantz and the Engine Sound Pack by TGModz include it in their lists of compatible trucks. The same author also made the Rezworth W900 and the Rezbilt Wheel Pack.

Version and status

The author doesn’t list a game version on the page. The latest update is from May 27, 2024. In comments from October 2026, several players say it hasn’t been updated in over two years. They also report bugs: the rear half of the glass is missing, you can see the road through the dashboard and some lights stay on. For news, the author points to his Facebook group.
