Riding the success of last year’s introduction of the Pace Arrow gas-powered A-body motorhome with a full-wall slideout, Fleetwood Enterprises Inc. expanded the patent-pending SpacePlus technology into its 2006 Discovery (pictured), Excursion and Providence diesel pusher lines. “This is a major breakthrough to offer this technology in diesels,” said Luc van Herle, motorhome product marketing manager. The Riverside, Calif., manufacturer debuted the new diesel coaches at the 43rd Annual National RV Trade Show in Louisville, Ky. The full-wall slideout is available in 39-foot models built on Freightliner XC chassis in all three diesel lines. Base retail prices are $206,200 for the Providence and Excursion, both powered by 350-hp Caterpillar C7 engines, and $193,200 in the 330-hp Discovery.
