And what was true then is even more so now, as a news release received recently spells out: Mile Hi Foods, a Denver-based refrigerated food service distributor that has 27 Vector units – second-generation Vector 6500s and multi-temperature 6600MTs – is generating huge savings using electric stand-by. By piggybacking on the unique diesel-electric Deltek hybrid architecture of the Vector units, this relatively small trucking operation is saving $85,000 per year and offering customers a smaller carbon footprint.
