Workhorse Custom Chassis has entered the competition in the diesel engine Class A motorhome chassis segment with the introduction Friday (July 19) of its R Series platform.
The R Series was unveiled by Workhorse during an industry gathering at Lake Las Vegas, Nev.
“Even though the R Series is a ground-up design, it still can be offered with many existing motorhome models,” said Richard Fish, vice president of motorhome sales and marketing for Workhorse. “We have worked closely with RV manufacturers to integrate our product with their current body design, helping to eliminate significant coach modifications.”
The R Series, which will go into production early in 2003, comes with a standard Cummins 350-horsepower (hp) engine coupled to Allison 3000 Series transmissions. Cummins 330- and 400-hp engines will be available as options.
The gross vehicle weight rating (GVWR) for the standard R Series is 28,000 pounds with an option of 31,000 pounds.
The wheelbase ranges from 208 to 256 inches.
Workhorse also partnered with suspension systems supplier ArvinMeritor to develop the integrated front and rear RideStar suspension system, an exclusive for the R Series. The trademarked RideStar system allowed Workhorse to lower and move the engine closer to the rear axle. The result is better handling and reduced driveline noise, according to Workhorse.
ArvinMeritor also positioned the front suspension system air bags ahead of the axle so the motorhome rides 100% on air for “exceptional handling and ride comfort with improved stability.”
“There’s a lot to this product, yet, it also incorporates elegant, simple design solutions,” Fish said. “One of our goals was to reduce the complexity of the chassis. Reducing complexity increases reliability, maximizes performance and provides more a customer and service-friendly platform.”
