Jazzycat truck pack is one of the best traffic pack mods, a must have if you like to see more truck models in your game and especially old trucks. besides personalized sound for all trucks in this pack, I increased the spawn of the old trucks and I adjusted max_speed and torque for some trucks. according to the game version you are playing you must have the following mods in the following order : for game version 1.32: 1. Old Trucks Ai Engine Sounds for Jazzycat truck pack 3.1.1 (unpack my archive) 2. Truck Traffic Pack v3.1.1 for 1.32: viewtopic.php?f=177&t=136930&start=350#p981532 for game version 1.31: 1. Old Trucks Ai Engine Sounds for Jazzycat truck pack 1.31 addon 2. Old Trucks Ai Engine Sounds for Jazzycat truck pack 3.1.1 3. Truck Traffic Pack v3.1 for 1.31: viewtopic.php?f=177&t=136930&start=330#p925533 if you want to keep the default spawn by jazzycat you could remove the folder def/country from my base mod this pack includes few sounds from Drive Safely’s pack Sound Fixes, mostly sound horns for which I offer to him well deserved credits in my mod changelog v1.1: corrected error in one file causing no spawn in 1.32 Credits: Cipinho, Drive Safely, Jazzycat
