Version and compatibility
The authors say it is tested on recent game versions, without naming one, and that it is compatible with most graphics and traffic mods. It was published on May 24, 2026 and last updated on October 18, 2026 (9 updates). It weighs almost 2 GB.
Keep in mind
The authors present it as a fan-made customization project with no ties to Kenworth, and call it a “free version”, although the page does not say where the full version is. In the comments some users say the cab is very dark at night, the engine sounds muffled and the steering is very sensitive; the author keeps fixing things with each update.
