York, Neb.-based King of the Road has upgraded the interior and exterior looks, power plant and basic superstructure of its 2-year-old, rear-engine Genesis Class A motorhome, the company’s first-ever motorized offering. “We’ve given it more strength to generate more of a box-truss system,” said Rodney Johnson, product design engineer for the Chief Industries Inc. division. “We build the box and then set it on the chassis rather than building the box on the chassis.” Available in four 40-foot floorplans with up to four slideout rooms, Genesis is built on a modified 34,320-pound GVWR Freightliner XM chassis powered standard by a 400-hp Cummins ISL diesel engine. Also revised were molded fiberglass front and rear end caps, one-piece windshields, side-hinged baggage compartment doors and cockpits with redesigned dashes. MSRP: $300,000.
