2004 Workhorse P30: Quick Overview
- Engine Options: The 2004 Workhorse P30 was typically equipped with General Motors V8 gasoline engines, most commonly a 5.7L Vortec or a larger 7.4L Vortec. Diesel options, such as the 6.5L Turbo Diesel, were also available, particularly in heavier-duty configurations.
- Horsepower: Horsepower varied significantly based on the engine. The 5.7L V8 typically produced around 250-260 horsepower, while the 7.4L V8 offered more grunt, generally in the range of 300-330 horsepower. Diesel engines were geared more towards torque, with figures often around 180-200 horsepower but with substantial torque for hauling.
- Fuel Economy: Fuel economy figures are notoriously poor and highly variable due to the chassis's intended use for heavy loads and large bodies. Expect single-digit to low double-digit MPG, often in the 8-12 MPG range, heavily influenced by the engine, transmission, and the weight of the upfitted body.
- 0-60 Times: 0-60 mph times are not a primary metric for this vehicle and are generally quite slow, often exceeding 15-20 seconds, especially when equipped with a fully built-out body and cargo.
- Towing Capacity: Towing capacity is substantial, designed to handle significant loads. This is highly dependent on the specific chassis configuration, rear axle ratio, and the type of body installed. It could range from 5,000 lbs to well over 10,000 lbs for properly equipped models.
- Trim-Level Features: As a chassis, the P30 did not have traditional trim levels in the passenger vehicle sense. Instead, features were dictated by the chassis package and the subsequent upfitter's choices for the body. Standard features on the chassis itself were basic and utilitarian, focusing on the drivetrain, suspension, and driver controls necessary for operation of a commercial or recreational vehicle. Optional features would be entirely dependent on the final vehicle build, such as power steering, power brakes, and air conditioning were common.

What Problems Does the 2004 Workhorse P30 Have?
The 2004 Workhorse P30, being a chassis designed for heavy-duty applications and often used in commercial or RV capacities, can present several frequently reported issues and long-term reliability concerns, largely stemming from its age and usage. One of the most common issues is related to the drivetrain, particularly with older automatic transmissions that may exhibit slipping or hard shifting, especially under load. The GM gasoline engines, while generally robust, can suffer from typical issues like intake manifold gaskets leaking coolant, or fuel pump failures over time. For diesel variants, injection pump problems and glow plug issues are not uncommon. A significant concern for many P30 owners, especially in rust-belt regions, is frame corrosion and rust on various chassis components. This can compromise structural integrity and lead to costly repairs. Brake systems, including rotors, calipers, and lines, will require regular maintenance and replacement due to the vehicle's weight and typical usage. Suspension components, such as ball joints, tie rods, and leaf springs, can also wear out prematurely given the constant stress. Electrical gremlins can manifest over time, affecting dashboard lights, power windows, or other accessories, often due to corroded wiring or failing components. While specific recalls for the 2004 model year are less common for the P30 chassis itself (as it was a platform, not a complete vehicle), any recalls would pertain to specific components supplied by manufacturers or issues identified by Workhorse. Long-term reliability heavily depends on the quality of the upfitted body and the maintenance regimen followed by previous owners. RVs built on this chassis, in particular, can experience issues related to the house systems (plumbing, electrical, appliances) as well as the chassis itself. The most critical aspect for potential buyers is a thorough inspection by a qualified mechanic familiar with heavy-duty vehicles and RVs, focusing on rust, drivetrain condition, and braking systems.
How long will the 2004 Workhorse P30 last?
The 2004 Workhorse P30 is built for longevity, with many units serving for 15-25 years or accumulating 150,000 to 300,000 miles. Its durability is heavily contingent on consistent and thorough maintenance. When properly cared for, with regular fluid changes, chassis lubrication, and prompt attention to wear items like brakes and suspension, these vehicles can prove exceptionally resilient. Weaknesses that emerge over time often relate to the aforementioned rust issues, especially in areas exposed to salt and moisture. The inherent wear and tear on heavy-duty components means that while the core powertrain is robust, auxiliary systems and bodywork will eventually require significant attention. The vehicle's longevity is a testament to its robust, no-frills construction, but owners must be proactive with maintenance to mitigate age-related degradation and ensure continued reliable service.
What Technology & Safety Features are Included?
The 2004 Workhorse P30, by its nature as a commercial chassis and platform for RVs and vocational vehicles, is not equipped with the advanced technology, entertainment, or driver-assistance features found in modern passenger cars. Its built-in tech is rudimentary, focusing on essential operational functions. The instrument cluster typically includes standard gauges for speedometer, tachometer (if equipped), fuel level, engine temperature, oil pressure, and battery voltage. Entertainment systems were generally aftermarket installations by the upfitters or owners, ranging from basic AM/FM radios to more complex stereo systems with cassette or CD players. Navigation and advanced infotainment were virtually non-existent. Driver-assistance features are minimal, limited to power steering and power brakes on most models, which were considered significant aids for managing a large vehicle. Some models might have had cruise control as an option. Safety features are also quite basic. Standard safety equipment would include seat belts for the driver and any factory-installed passenger seats. Airbags were not standard on all configurations of the P30 chassis and often depended on the specific upfit or customer order. ABS (Anti-lock Braking System) was an optional feature that became more prevalent in later years of its production. Due to its status as a chassis and platform for various vehicles, standardized crash-test ratings for the 2004 Workhorse P30 itself are not readily available in the same way they are for consumer vehicles. The safety performance would be largely determined by the final body construction and any integrated safety systems added by the coachbuilder or RV manufacturer. Upfitters might have added features like rear-view cameras, particularly for RV applications, but these were optional and not integrated into a sophisticated system. In essence, the P30 is a utilitarian foundation, and any modern technological or safety enhancements would be owner or upfitter additions.

Performance: The P30 often offered more robust engine options and a heavier-duty frame than typical van chassis, making it superior for heavier loads. Ford's E-Series chassis, especially the Super Duty variants, offered comparable engine power and towing. Chevrolet's offerings were generally less robust for the heaviest applications.
Features: Feature-wise, the P30 was a barebones chassis. Both Ford and Chevrolet offered similar levels of basic functionality. The true 'features' came from the upfitters (RV manufacturers or custom body shops), making direct comparison difficult. In terms of technological integration, all were rudimentary by today's standards.
Reliability: Reliability is a mixed bag for all these platforms from this era. The P30's heavy-duty construction lends itself to durability, but age-related issues like rust and worn components are common across all brands. Workhorse sometimes had specific transmission or engine concerns depending on the OEM components used. Ford's Triton V10 had its own set of issues, and Chevrolet's Vortec engines were generally reliable but might lack the raw power of larger options.
Price: New, the P30 chassis was competitively priced against its heavy-duty competitors. Used, the market is highly dependent on the condition of the chassis and the quality of the conversion. A well-maintained P30 can offer good value for its capability.
Alternatives: For RV applications, Ford E-Series cutaway chassis (e.g., E-350, E-450) are very common and offer a comparable if not sometimes superior option, especially with the V10 gasoline engine. For lighter-duty commercial vehicles, Ford Transit Connect or Ram ProMaster might be more modern, fuel-efficient, and feature-rich alternatives, though they cannot match the P30's heavy-hauling capabilities. If seeking pure workhorse utility and don't need RV amenities, older heavy-duty pickup trucks or purpose-built medium-duty trucks might also be considered, though their driving dynamics differ significantly.
