MACS members, and those who should be MACS members, are increasingly working on more heavy duty and off-road vehicles. The MACS database is full of trucking, fleet, agricultural, mining and industrial vehicle businesses. In response, MACS  will be presenting a series of top shelf, high-value training events for the heavy duty and off-road vehicle mobile A/C technician. Acclaimed heavy duty A/C trainer, Blake Gordon will focus a training session on the idiosyncrasies of servicing A/C systems in heavy duty and off-road vehicles along with a hands-on training session.  Continental breakfast and lunch are included.
