I want to know everything there is to know about mack trucks. I am a shop manager at a heavy duty garage and my employer own 25 different makes models and years of Mack trucks. My initial Mack training involved a computer and alot of repeated sensor changing. After a few years I've learned the preventive maintenance of the trucks solves most of your so called sensor/wiring malfunctions. I love to read the posts on here. And as luck would have it I'm a Mack guy all the way.
