It returns; several people contacted me after I stopped updating the engine pack. I have now decided to update it and release it.
Please be aware that this mod is updated for game version 1.22.x which at the time of writing is still in open beta. This mod will crash your game if you attempt to use it on 1.21.x or older.
The pack includes one or more engines for all trucks except the Mercedes MP4. The Volvo 2012 also includes the alternate stock grill colours for most default engines.
