389 peterbilt v1.1

Updated and enhanced version of the serious mods 389 peterbilt.  Has some tweaks to the sound pack since some items were missing. Added a jake brake that works when the keypad button 0 is hit. New train hornadded.  Added different fenders rather than the black fiberglass full fenders on the original. Added many new marker lights on side and front bumper. Special thanks to rt_40 for the convert and seriousmods for the original truck. Enjoy
