After more then a year this combo is complete now. In scale 1:13 this combo is completely build out of genuine Lego bricks (about 17.000). As an addition many where chromed afterwards in an electroplating process, becoming truly chromed.
This truck is mildly based on the fleet of Eilen trucking. The rig is a Peterbilt 379 with extended hood and C15 CAT engine, also heavily chromed. The trailer is a MAC half round enddump.
