I made a model of the Fiat 682 N4 truck in two variations, this is a regular body (red) and with additional sides (green). This was a mod of an old truck from Farming Simulator 22.
In the model, everything inside the cabin is animated, just as it should be in real life. Everything is fine outside too.
Fiat 682 N4 mod made for FS 23 Trucks. It has the original sound of the engine, gear shifting and the hum of the drive axles.
