“The only RTA mod that doesn’t crash my game is the Mack”
Also, there are sound and engine errors in that log for the K200 and 108. I did some snooping around in the sound archives that ship with the various trucks.
It’s important that -all- the sound packs are present and active for -all- the relevant trucks.
Here’s a brief list:
Sound_Pack_2_v1.2: Western Star 4800, Cat 660, Mack Superliner, Peterbilt 359
Sound_Pack_1_v1.2: K108, K200, T609, T908
Sound_Pack_4_v1.0: Peterbilt 379

If you -don’t- have Sound_Pack_1 present, but -do- have Sound_Pack_2 present, then your Mack will load properly, but the K200, K108, T609 or T908 will crash the game.
This means that if you have 4800, K200 and Pete 379 active in your game, you need all three sound packs listed above.
I don’t know if you already have this in place, but I can’t assume anything 🙂
