No you don't need to download the sound mod from kriechbaum again in order to use this truck. The engine sound is integrated into my work and ready for use. And to answer your PM question @Derwin, yes the sound is up-to-date, as of the moment I wrote this.
like i said exterior looks awesome, hope we will get a as good looking interior in the future
also, little advice for the shadow, move it up further, every time if the player brakes or starts to drive reverse the shadow is sinking into the ground
