I took a light version of the class at Spartan in 2003 and it was excellent. They had a bare chassis and their technician walked around it explaining the features, locations and adjustments. They gave handouts of chassis electrical and chassis mechanical. The technician hung around and answered many of my questions one on one. Look at the two sites below.
