Choosing the Right Utility Body for Work Trucks

[MikePhua]

The Role of Utility Bodies in Field Operations
Utility bodies transform standard pickup trucks into mobile workstations, enabling technicians, contractors, and tradespeople to carry tools, parts, and equipment in an organized, secure manner. These bodies replace the traditional bed with compartmentalized storage, often featuring lockable cabinets, reinforced floors, and ladder racks. Whether used in masonry, electrical work, excavation, or fleet maintenance, the right utility body can dramatically improve efficiency and reduce downtime.
Comparing Stahl and Reading Utility Bodies
Two of the most recognized manufacturers in the utility body market are Stahl and Reading. Stahl, founded in 1946 in Wooster, Ohio, built its reputation on rugged steel bodies tailored for municipal and industrial fleets. Reading, established in 1955 in Pennsylvania, pioneered the use of aluminum in service bodies and remains a leader in corrosion-resistant designs.
Reading bodies are known for their stainless steel latches, concealed hinges, and powder-coated finishes. These features reduce rust and wear, especially in humid or coastal environments. Stahl bodies, while equally durable, tend to use more traditional hinge designs and heavier steel construction, which can increase payload but also add weight.
In terms of longevity, Reading’s aluminum options often outlast steel counterparts, especially when exposed to road salt or chemical runoff. However, Stahl’s heavier gauge steel may be preferred in applications involving frequent impacts or heavy-duty hauling.
Aluminum vs. Steel Racks and Payload Considerations
One of the most debated topics in utility body customization is the choice between aluminum and steel ladder racks. Aluminum racks, such as those made by System One, offer significant weight savings—often 150 to 200 lbs less than steel alternatives. This reduction is critical for single rear wheel (SRW) trucks, which have limited payload capacity compared to dual rear wheel (DRW) models.
Operators who frequently haul materials like scaffolding, conduit, or lumber benefit from aluminum racks due to their resistance to rust and ease of installation. Steel racks, while stronger in some cases, require regular maintenance and are prone to corrosion, especially in northern climates where road salt is prevalent.
A contractor in Pennsylvania shared that his aluminum rack had survived eight years of heavy use, including overloaded hauls and exposure to harsh winters. He noted that while steel racks may appear sturdier, the real-world durability of aluminum exceeded expectations.
Interior Modifications and Rust Prevention
To extend the life of utility compartments, many operators install oil-soaked plywood at the base of each cabinet. This simple modification helps prevent condensation buildup and rust formation, especially in steel-bodied units. Some go further by lining the interior walls with aluminum diamond plate, which adds durability and improves aesthetics.
Rounded compartment designs, such as those found in Reading’s Aerotech series, may slightly reduce usable space but offer better water runoff and easier cleaning. These design choices reflect a shift toward ergonomic and maintenance-friendly features in modern utility bodies.
Vehicle Compatibility and Configuration Tips
Utility bodies are commonly installed on heavy-duty pickups like the Chevrolet 3500, Ford F-350, and GMC 3500. When selecting a body, it’s essential to match the configuration to the truck’s drivetrain and suspension. For example:
• SRW trucks benefit from lighter aluminum bodies and racks
• DRW trucks can support heavier steel bodies and larger payloads
• 4x4 models may require modified mounting brackets due to frame height
Operators should also consider cab style—extended cabs may limit rack length or require custom brackets. A technician in New York noted that his extended cab Chevy 2500HD required a shortened rack to avoid rear window obstruction.
Terminology Clarification
• SRW (Single Rear Wheel): Trucks with one wheel on each side of the rear axle, offering lower payload but better maneuverability
• DRW (Dual Rear Wheel): Trucks with two wheels per side on the rear axle, increasing payload and stability
• Utility Body: A replacement for the standard truck bed, featuring built-in compartments and tool storage
• Ladder Rack: A frame mounted above the utility body for carrying long materials like ladders or piping
Manufacturer Background and Market Reach
Reading Truck Group, now part of JB Poindexter & Co., produces thousands of utility bodies annually and distributes through a nationwide dealer network. Stahl, acquired by Scott Fetzer Company, focuses on fleet and municipal contracts, with a strong presence in the Midwest and South.
In 2023, Reading reported a 12% increase in aluminum body sales, driven by demand from telecom and electrical contractors. Stahl’s steel bodies remain popular among utility companies and heavy construction outfits.
Operator Insights and Anecdotes
A mason in Connecticut shared his experience outfitting a new Chevy 3500 with a Reading body and aluminum rack. He praised the concealed hinges and noted that the stainless latches held up well against concrete dust and moisture. Another user in New Jersey reported that his four Reading bodies had outlasted two trucks, thanks to regular oiling and interior plywood lining.
In Canada, a contractor questioned the use of aluminum racks on work trucks, citing concerns about strength. However, his counterpart in Pennsylvania countered with examples of aluminum dump beds on triaxle trucks, arguing that modern alloys are more than capable of handling abuse.
Recommendations for Buyers
When selecting a utility body, consider the following:
• Choose aluminum for corrosion resistance and weight savings
• Opt for stainless steel latches and concealed hinges for durability
• Line compartments with oil-soaked plywood or diamond plate
• Match body weight to truck payload capacity
• Use modular racks for flexibility and future upgrades
Final Thoughts
Utility bodies are more than storage—they’re the backbone of mobile operations. Whether hauling tools to a jobsite or managing a fleet, the right configuration can make or break productivity. With thoughtful selection and smart modifications, a utility body becomes an extension of the crew, built to endure the rigors of real-world work.
