I’ve been thinking of having a Sisu M series in the game for awhile. I don’t have the knowledge of cad software/blender to make it.

What I’m looking to do
•Have a Sisu M series (more specifically a M-162 6x2)
•Startup, idle, drive, and shutoff sounds of a Rolls Royce 320 MkIII (optional engine in these trucks)
•6 or 12 speed trans (6 speed for only high gears, 12 speed for High and low gears)

What are the thoughts of it?
