I had the opportunity to watch this truck being modified for service for Sterling Rescue. Medical Support Unit 615 is housed at the Kincora Safety Center (Sterling Rescue Station 35). MSU 615 is a 2004 Ford E350 with a 15' box built by "Complete Truck Bodies". The truck was purchased in 2013 in the Winchester area. Keplinger Repair, also located in Winchester, modified the truck as a Medical Support Unit. The new MSU 615 replaced a 1997 trailer operated by Sterling Rescue.
MSU 615 has the capability to treat 75 patients. In the rear is a lift gate to support operations. Other work completed on the truck included warning lights, siren, scene lights, interior lighting, body work, painting, lettering, interior shelving/compartments, and the addition of a 6kw generator.
Some of the medical supplies carried include LP12, suction devices, trauma supplies, and rehab equipment.
