Electric fireplaces are standard in KZRV LP’s new 2011 StoneRidge fifth-wheel series, including one floorplan with back-to-back fireplaces that divide the livingroom and the kitchen. ”Our market is the more mature RVer — someone who is at or near retirement,” said Andy Baer, vice president of sales and marketing. Introduced with four 34- to 38-foot floorplans at the 2009 Louisville Show, KZ will debut two new layouts during the company’s dealer open house May 17-18 at its Shipshewana, Ind., factory. The fiberglass-and-aluminum widebody StoneRidge, with three or four slideouts, features front and rear fiberglass caps, gel coat exteriors and Corian countertops for a $55,000 base MSRP. Also at the open house, KZ will reintroduce the high-end Escalade fifth-wheel which has been in hiatus and a redesigned version of the Durango fifth-wheel series.
