Freightliner's new SD (Severe Duty) models are beginning to show up on the streets. This SD 114 (114" bumper to back of cab) is fitted for roll off dumpster service. It is distinguished from the 108 SD model by having dual headlights. The 108" version has single lights.
Stiff competition from the likes of Volvo/Mack and now Cat, and of course the absence of Daimler's own Sterling brand, has encouraged FL to get into a market that it was never particularly noted for - the severe duty service in ready-mix, and refuse type work, but also to make those models readily distinguishable from its other lines.
Western Star still seems to be the leader in this area (also a Daimler product) but that is nothing new for the big multi-nats to have competing brands in their own stable.
