RKI Service Bodies: Houston-Built for Texas Work Trucks

When you need a service body that’s engineered for the Texas work environment, RKI (Rawson-Koenig) is a brand worth serious consideration. RKI service bodies are manufactured in Houston, TX — not shipped in from the Midwest or the coasts — which means faster lead times, strong regional dealer support, and bodies that are designed with Texas heat, humidity, and job site conditions in mind. At Star Truck Equipment in Wharton, TX, we install and supply RKI service bodies for contractors, oilfield operators, utility companies, and tradespeople across Texas and Louisiana.

What Makes RKI Service Bodies Stand Out

RKI’s service bodies are built for the working trades — not just for cosmetics. The lineup covers a wide range of configurations designed to match the specific needs of different industries:

  • Heavy-gauge steel construction: RKI bodies are built with 10-gauge or better steel on structural components. They hold up to the abuse of daily job site use, heavy crane loads, and rough lease roads.
  • Crane-ready configurations: RKI offers crane-ready service bodies with factory-engineered outrigger pockets and subframe reinforcement. These are paired with Tiger Cranes for complete service truck builds that go to work on day one.
  • Configurable compartment layouts: Whether you’re a plumber with specific pipe storage needs, an electrician with conduit requirements, or an oilfield service tech who needs fast-access tooling, RKI offers compartment configurations that put your gear where you need it.
  • Aluminum and steel options: For buyers managing payload on SRW chassis (Ford F-350, Ram 3500), RKI’s aluminum service body options save 200–400 lbs vs. all-steel builds — keeping you in compliance and extending tire and suspension life.
  • Powder-coat finishes: Standard RKI service bodies arrive with a durable powder-coat finish in black or work-grade colors. No galvanized coatings — these bodies are designed for the Texas work truck aesthetic and easy touch-up in the field.

RKI Service Body Models and Configurations

RKI builds service bodies in both steel and aluminum with body lengths ranging from 8 feet to 14+ feet, depending on the chassis. The most common configurations we see in Texas:

  • Standard service body (9–11 ft): The workhorse layout. Three compartments per side, top boxes optional, full-length headboard. Fits Ford F-350/F-450, Ram 3500/4500, Chevy Silverado 3500/4500 HD. Best for plumbers, electricians, HVAC techs, and general contractors.
  • Extended service body (12–14 ft): Designed for chassis cabs — Ford F-550, Ram 5500, and medium-duty platforms. More compartment space, more payload capacity, crane-ready subframe options. Popular with oilfield service companies and utility contractors.
  • Crane body configuration: Paired with a Tiger Crane (6,000–15,000+ ft-lb capacity), the RKI crane-ready service body creates a complete field service truck. Used by pipeline contractors, utility companies, and oilfield operators across South Texas and the Gulf Coast.
  • Contractor layout: High-density upper compartments, deeper lower compartments for power tools and large equipment, optional pipe racks or ladder racks over the cab. Common for construction and heavy trades.

What Trucks Does the RKI Service Body Fit?

RKI service bodies are engineered for a wide range of chassis:

  • Ford F-350 SRW / DRW: 9–10 ft body, aluminum or steel, excellent for lighter-duty trades. CA (cab-to-axle) of 60″+ recommended for a clean fit.
  • Ford F-450 / F-550: 10–12 ft body, crane-ready options available, higher payload ratings support heavier compartment loading.
  • Ram 3500 / 4500 / 5500: Strong fitment across the lineup. Ram chassis cabs (4500/5500) are popular with oilfield and utility buyers who want a purpose-built work platform.
  • Chevy Silverado 3500HD / 4500HD: Available in SRW and DRW configs. The 4500HD is an underutilized platform for service body work — it fits a 10–11 ft body cleanly and handles payload well.

RKI Service Bodies vs. the Competition

RKI competes directly with STI, CM, and national brands like Knapheide in the Texas service body market. Here’s the honest breakdown:

  • RKI vs. STI: STI builds some of the most heavy-duty crane bodies and mechanics trucks in the market — great for oilfield and heavy construction. RKI is more broadly focused on standard service body applications, often at a more competitive price point for mid-duty commercial work. See our RKI brand page for full lineup details.
  • RKI vs. CM: CM’s service body lineup (SB, SSB, SBF) is lighter-duty and well-suited to pickup trucks in the F-250/Ram 2500 range. RKI goes heavier with crane-ready and chassis-cab configs. If you’re outfitting a commercial fleet on F-350s or bigger, RKI is often the better fit.
  • RKI vs. Knapheide: Knapheide has a massive national dealer network and wide product breadth. RKI is Texas-built, often has shorter lead times for Texas buyers, and offers more direct technical support through regional dealers like Star Truck Equipment.

Pricing and Lead Times

RKI service body pricing varies significantly by configuration, body length, and material (steel vs. aluminum). As a rough guide for planning purposes:

  • Standard steel service body (9–11 ft): $4,500–$7,500 installed, depending on options and chassis
  • Extended steel service body (12–14 ft, chassis cab): $6,500–$10,000+ installed
  • Crane-ready configuration + Tiger Crane: Total builds typically range from $15,000–$30,000+ depending on crane capacity, body size, and chassis
  • Aluminum service body: Adds approximately $1,000–$2,500 vs. comparable steel body

Lead times from Star Truck Equipment in Wharton, TX are typically 2–6 weeks depending on body configuration and current inventory. Call us for current availability — we often have RKI bodies in stock or available for rapid delivery through our Houston-area supplier network.
