Scania R tractor unit v1.0.0.0

Moin moin, before I start to tell you what about this truck, I would like to ask for help. More details I will explain below.
The Scania has various configs.
3 bull catchers
Color
Company logos
Ouffler
Underbody bar
Motor with 2 different transmission types
Stone impact protection
Detail faithful interior lighting
Controllable chassis, rear separate and once complete (controllable via the right mouse button)
Sound is from the game, nevertheless the sounds were put together new for this truck
My log is clean, I strongly assume that it is the same for others, but should errors occur, gladly also here a PN.
