Spartan Motors Inc. announced today it has introduced the Summit ES, a diesel pusher chassis costing 10% to 15% less than the Summit series units it introduced during 1998 and 1999.

Rexhall Industries Inc., Lancaster, Calif., will introduce a new Class A motorhome on the Spartan Summit ES, said John Sztykiel, president and chief operating officer of Spartan.

“The new ES platform allows original equipment manufacturers such as Rexhall to build a motorhome with all the features, performance and maneuverability of higher-priced models, but with a sticker price of less than $100,000,” Sztykiel said.

The Summit ES platform was built for motorhomes up to 38-feet long. It features a Cummins ISB 260-hp engine, Allison 1000 Series transmission and air suspension as standard equipment.

Other so-called “entry-level” diesel pusher chassis use spring suspensions, Sztykiel said.

Air ride better handles the weight distribution issues that arise with the inclusion of slide-out rooms, Sztykiel said.

Spartan Motors plans to introduce another new motorhome chassis during the RV industry’s national trade show in Louisville next November, he added.
