Spartan Motors Inc. has been named the sole chassis supplier for Winnebago Industries Inc.’s Ultimate Freedom and Ultimate Advantage series of high-line diesel pusher motorhomes beginning with model year 2002.

The initiative should translate to Spartan supplying 300 to 400 chassis to Winnebago during model year 2002, according to Spartan.

The first 2002 Ultimate Advantage built on a Spartan chassis rolled off the assembly line in May.

Winnebago’s Ultimate Freedom has been built on Spartan chassis since model year 2000.

“The Ulti-Bay chassis featured on the Ultimate series is unique in that both Winnebago Industries and Spartan participated in the platform design and build, resulting in an exceptional chassis for this RV application,” said Bruce Hertzke, Winnebago’s chairman, president and CEO. “This unique diesel pusher chassis is custom-designed to maximize handling characteristics and storage, resulting in a true top-of-the-line coach.”
