2006 WORKHORSE W22: Quick Overview
The 2006 WORKHORSE W22 chassis is characterized by its heavy-duty nature, designed to be the backbone of larger recreational vehicles. As a chassis, it doesn't have traditional trim levels like a passenger car; instead, its features are dictated by the RV manufacturer building upon it. However, the core specifications of the chassis itself are as follows:
- Engine Options: The primary engine for the 2006 Workhorse W22 was typically a General Motors Vortec V8 gasoline engine or, more commonly for RV applications requiring more power and torque, a turbodiesel engine. A prevalent diesel option was the 7.2L Caterpillar C7, known for its robust performance. Other diesel options might have included engines from Cummins or International, depending on the specific RV model and configuration.
- Horsepower: Horsepower ratings varied significantly by engine. The Caterpillar C7, for instance, could produce upwards of 300-330 horsepower. Gasoline Vortec V8s would typically be in the 300-350 horsepower range.
- Fuel Economy: Fuel economy for a chassis of this size and purpose is generally low, especially when loaded as a motorhome. Expect figures ranging from 8 to 12 miles per gallon (MPG) for diesel engines, and potentially lower for gasoline engines.
- 0-60 Times: Official 0-60 mph times are not typically published for chassis platforms as they depend heavily on the final weight and configuration of the completed RV. However, due to their substantial weight, acceleration is generally slow, prioritizing stability and torque over speed.
- Towing Capacity: The towing capacity of a 2006 Workhorse W22 chassis is substantial, designed to handle large trailers and towed vehicles. This capacity would be specified by the RV manufacturer and could range from 5,000 lbs to over 10,000 lbs, depending on the Gross Combined Weight Rating (GCWR) and Gross Vehicle Weight Rating (GVWR) of the specific chassis and the resulting motorhome.
- Chassis-Level Features: Key features inherent to the W22 chassis include a heavy-duty suspension system designed for stability and load-carrying, robust braking systems (often hydraulic or air-assisted), power steering, and a comprehensive electrical system to support the coach's amenities. RV manufacturers would then integrate their own amenities, driver controls, and living quarters upon this foundation.

What Problems Does the 2006 WORKHORSE W22 Have?
The 2006 WORKHORSE W22 chassis, while generally considered a solid foundation for RVs, has had some commonly reported issues and areas of concern that owners should be aware of. One of the most frequently mentioned points of attention involves the transmission, particularly the Allison transmissions often paired with diesel engines. While Allison transmissions are renowned for their durability, specific issues like occasional rough shifting, premature wear of seals, or even failure of the torque converter have been reported, though these are often tied to mileage, maintenance, and how the vehicle has been operated.
Another area that sometimes requires attention is the braking system. Due to the significant weight these chassis carry, brake components such as rotors, pads, and calipers can experience accelerated wear. Some owners have reported issues with brake fade on long descents or premature failure of brake lines or hydraulic components. Regular inspection and maintenance of the braking system are paramount.
Exhaust manifold leaks are another recurring concern for some Workhorse chassis, including the W22. This can manifest as an audible ticking sound, particularly when the engine is cold, and can lead to reduced engine performance and increased fuel consumption if not addressed. Cracked exhaust manifolds or failed gaskets are the usual culprits.
While specific recalls for the 2006 model year are not as broadly documented as some other vehicle types, it's always prudent for owners to check with Workhorse or a qualified dealer for any outstanding safety campaigns that might apply. Long-term reliability is largely dependent on the quality of the RV conversion and the ongoing maintenance of both the chassis and the coach components. Engines like the Caterpillar C7, when properly maintained, can be very reliable, but they are complex and require specialized knowledge for repairs. Neglecting fluid changes, filter replacements, or ignoring warning signs can significantly impact the longevity of both the engine and transmission. The overall lifespan of a W22 chassis can be extensive, often exceeding 200,000 miles if well-cared for, but the cost of major repairs can be substantial.
