Freightliner subsidiary Thomas Built Buses, the C2 chassis departs from previous precedent in its higher parts commonality with the M2 106 truck. Forward of the driver's seat, the dashboard is used in its entirety; while the windshield is redesigned (enlarged), the stock windshield wipers are retained. Outside of school bus use, Freightliner designates the cowled bus chassis as the Freightliner S2; the model is no longer offered on the Freightliner chassis website. The Freightliner S2C is the cutaway-cab variant of the M2. Never produced with a school bus body, the S2C was intended for various commercial uses, including shuttle and transit bus use. A variant of the S2C cab chassis known as the S2RV is also used as a platform for midsize to large Recreational vehicles. Severe-service trucks As with the FL-Series, Freightliner developed severe-service variants of the Business Class M2. While the M2 106V and M2 112V would share the same cabs and hood as the medium-duty vehicles, they were based on their own unique chassis. In 2011, Freightliner replaced the M2 106V/112V with the "SD" line of severe-service trucks, dropping them out of the Business Class M2 model range. While the 108SD and 114SD still used the M2 cab, an all-new hood and chassis was used. Aftermarket Freightliner Specialty Vehicles (also known as SportChassis LLC) is a manufacturer based in Clinton, Oklahoma that produces conversions of the Business Class M2 as consumer vehicles. Several vehicles are available, including 5th-wheel tow vehicles and pickup trucks. While similar in layout to the International CXT/RXT, these differ in that they are completed by a second-stage manufacturer.
