New in version 1.6:
– Fixed interior meshes and textures
– Additional tuning options (fenders, tanks, aerodynamic wings, interior upholstery color)
– Some parts were removable from the truck, fixed now
– Fixed some sound files and scripts
– Engine model outside is now bound to the actual engine installed (orange CAT and red ISX)
– Hood Mirrors made more realistic
– Fifth wheel adjustments (mod trailers compatibility not guaranteed)
– New high definition gauges made by Imperator3
– Great Fire-themed paintjob made by Pauly
– All known bugs have been catched (more to come i guess…)
