Diesel pusher chassis supplier Spartan Motors Inc. now is producing Intelligent Suspension System (ISS) equipped chassis for use by motorhome builders on their 2003 model year units.
The ISS will debut on a 2003 American Eagle highline Class A motorhome that will be introduced by Fleetwood Enterprises Inc. at the Family Motorcoach Association (FMCA) convention that opens Tuesday (March 19) in Perry, Ga.
Spartan executives believe motorhome suspension technology “turned an important corner” with the introduction of ISS. It will provide motorhome owners with improved cornering and handling by continually adjusting to the configuration of the road. It combines hydraulics with electronic sensors and computer control to provide a “tight, level and smooth motorhome ride under all conditions,” according to the Charlotte, Mich.-based company.
“The ISS is replacing ride-control technology that hasn’t changed in decades,” said John Sztykiel, president and COO of Spartan. “The old systems — which are essentially shock absorbers and anti-sway bars — could be tuned to only one setting, and engineers had to guess at what would be a comfortable compromise between a bumpy ride with little sway, or a smooth ride with a lot of sway.
“By comparison, ISS continually monitors the road and vehicle conditions, and the result is a smooth, level ride that is unparalleled in the RV industry,” Sztykiel added. “ISS should significantly improve both Spartan and Fleetwood’s position in the RV market.”
