I don't own the vehicle body or fixtures so all credits to the original makers.
Adjusted files to make the truck sound and act like it was steam powered. I usually just leave it in first gear all of the time and just put it in low range for off-road. I'm pretty proud of this MOD, I had no major help so it took me a long time to get it to work the way I wanted.
Turbo is only there to add some more sounds.
Hope you enjoy
