K-DOG's Trucking + Trucks 1.49

It has just come to my attention that there is no sound for the truck engines. This is caused by a long known but
forgotten problem with engine sounds and zip files, they don't mix. To fix this simply unzip the mod in your mod folder, using whatever zip app you use, use the, extract to: "the mod name" and it should create a folder named the same as the mod, then delete or move the original mod zip file.
