Optimus Prime Western Star truck was the prime attraction at an Open House hosted at Johnson Truck Center’s Landover facility on August 22, 2017.  The weather cooperated and many customers even brought their children along to have their picture taken next to the movie star vehicle.  Vendors for Johnson Truck Center were on hand to discuss truck purchases of the newest Freightliner, Western Star and Autocar models, ask questions of Daimler Finance, check out used truck inventory, or learn more about aftermarket solutions from Donaldson, Weller, Allison, Alliance Parts and other well-known brands.  The food from Mission Barbecue was a hit and everyone enjoyed free ice cream selections from the Good Humor truck.   Seminars focused on aftertreatment and DPF issues as well as safety concerns like electronic data logging.
