2002 Winnebago Adventurer

This 2002 Workhorse W22 Chassis is a motorhome foundation built for heavier applications within the Workhorse line. It is associated with the W22 series, which was used under a range of larger RV bodies during the early 2000s. This chassis places the emphasis on the underlying running gear rather than on cosmetic presentation, and its identity is tied to the components that support the coach above it. The model year and designation are the key identifying details, and they define the vehicle more clearly than any added description would.

This chassis was built around a truck-based frame intended for motorhome use, and it reflects that purpose in its construction. The W22 designation indicates a 22,000-pound gross vehicle weight class, which places it in the heavier segment of gas-powered RV platforms from that period. This class of chassis was commonly paired with larger body styles, and the frame, suspension, and brake system were selected to match that role. Workhorse used this platform as one of its mainstream offerings before later revisions to its motorhome underpinnings, and this 2002 example belongs to that earlier generation of production.

This chassis is known for its General Motors-supplied gasoline powertrain architecture, which was standard for the W22 line in that era. This version used an 8.1-liter Vortec V8, and the drivetrain was matched to a heavy-duty automatic transmission. The engine family is one of the most recognizable parts of the platform, and the transmission pairing was typical of the Workhorse gasoline motorhome range. This combination was selected to handle sustained load in a large coach application, and it remained one of the defining mechanical features of the series throughout the early 2000s.

This chassis includes components that were common to its class, such as large-diameter wheels, substantial braking hardware, and a suspension intended for motorhome service. This platform was also part of an era when Workhorse supplied dedicated RV chassis with components tailored to that segment rather than adapting a light-duty pickup frame. The W22 designation places it in the higher-capacity portion of the lineup, and that rating shaped how it was used by coach builders. This 2002 example is a straightforward representation of a purpose-built motorhome foundation from the period, with the major value lying in its documented mechanical specification and weight class.
