STI (Service Truck International) and Knapheide are two of the most recognized names in service bodies — but they serve very different markets. If you’re speccing a service truck for Texas or Louisiana work, here’s an honest breakdown of how these two brands compare and which one is the right fit for your operation.

STI: The Heavy-Duty Texas Choice
STI (Service Truck International) is built in Waco, TX — right in the heart of the Texas market. Their service bodies are designed for extreme-duty oilfield and heavy construction applications where a standard service body simply won’t cut it. STI’s lineup includes service bodies, crane bodies, mechanics trucks, lube trucks, and fuel service bodies — a complete heavy-duty work truck ecosystem.
Where STI Wins
- Texas-made for Texas work — STI understands Eagle Ford shale, Gulf Coast humidity, and Permian Basin punishment
- Crane body specialization — STI crane bodies are factory-matched for Tiger Crane integration, creating seamless crane truck builds that Knapheide can’t match locally
- Complete service truck lineup — Lube trucks, fuel service bodies, and mechanics trucks alongside service bodies
- Local availability and support — Available at Star Truck Equipment in Wharton, TX — you can spec, buy, and service your truck close to home
- Oilfield-proven durability — Heavier-gauge construction for the toughest field conditions
Knapheide: The National Fleet Standard
Knapheide (Quincy, IL) is the largest truck body manufacturer in North America by volume. Their KUV (Knapheide Utility Vehicle) service bodies are the standard on thousands of utility, telecom, and municipal fleets across the country. If you’ve seen a service truck on a power company, phone company, or government fleet, there’s a good chance it’s wearing a Knapheide body.
Where Knapheide Wins
- Broadest body type selection — Service, utility, platform, dump, crane, mechanics, landscaper — Knapheide builds more body types than almost anyone
- National fleet standardization — If your company runs Knapheide nationally, local TX/LA trucks should match
- Municipal and utility company track record — Deep relationships with large utility and government fleets
- Lower entry-level price point — Standard KUV models are competitively priced for basic service body needs
Knapheide Considerations for Texas Buyers
- Not the ideal choice for oilfield crane builds where STI + Tiger Crane combo is purpose-built
- Knapheide dealers in South Texas are limited vs national footprint
- Standard service bodies may not meet the heavy-gauge requirements of oilfield and pipeline abuse
- Lube truck and fuel service body options are more limited than STI
Which Should You Choose?
Choose STI If You:
- Are in the Texas or Louisiana oilfield, pipeline, or heavy construction market
- Need a crane body with Tiger Crane integration
- Want locally available dealer support in South Texas (Wharton, TX area)
- Need a lube truck, fuel service body, or mechanics truck
- Run chassis cabs (F-450+, Ram 4500+) in demanding field conditions
Consider Knapheide If You:
- Operate a national or regional fleet that’s already standardized on Knapheide
- Need a municipal or utility company service body matched to existing fleet specs
- Have access to a Knapheide dealer and prefer their sales/service relationship
- Run F-150 through F-350 SRW trucks for lighter-duty service work
