With the exception of the scripts, which I was unable to unlock or decrypt, therefore they are deactivated in the registration, the unpacked DLC Mercedes-Benz Trucks Pack has not altered much and still includes all the required tools and equipment.
I added an IC Control for five automobiles (not on tractors) and a beacon beam for three cars with a choice of glass colors.
