"Turn up the volume of your sound system and drive for hours w/Cat C-16 690hp tuned..."

-> Max out Truck engine, exhaust volume. 
-> Turbo volume, effects, noise, interior sounds etc. at ~90 percent. Find your sweet spot.

-> 'No sound' issue: Sell truck, drive in-game truck, buy truck again, then there's sound.

Fixed, Updated, Upgraded by Kenworth_John 2021:

- New: Caterpillar C-16 tuned SP, fan noise! - handmade torque curve, real life specs
- Adapted Eaton 18-speed transmission with retarder for working smoothly with C-16
- Sounds fixed. Many missing files, many wrong data paths in mod.
- Changed base/fallback model at dealer for a more satisfyingly look.
- Again and again: Shadows, reflections, textures needed some attention.
- SCS-ingame and BigBob-Bumbers caused map errors due to missing side reflections. Corrected!
- And much more details... a never ending story. This project got bigger than expected.

Tested for hours now. Works very good without crashes/issues. Also tested w/clean profile.
