When it comes to heavy-duty service truck bodies for oilfield, construction, and utility work in Texas and Louisiana, two names come up constantly: STI (Service Truck International) and Maintainer. Both build serious work trucks — but they’re built for different buyers with different needs. Here’s an honest breakdown.

STI Service Truck Bodies: Built for Texas Oilfield and Heavy Construction
STI (Service Truck International), headquartered in Waco, TX, builds one of the most comprehensive heavy-duty service truck body lineups in the country. Their models span standard service bodies, crane bodies, mechanics trucks, lube trucks, and fuel service trucks — all designed for the kind of heavy use that Texas and Louisiana oilfield, pipeline, and construction companies demand.
STI Strengths
- Texas roots — Built in Waco, TX, and available locally at Star Truck Equipment in Wharton, TX
- Full body type lineup — Service bodies, crane bodies, mechanics trucks, lube trucks, and fuel service bodies under one roof
- Factory crane-ready configurations — STI crane bodies are purpose-built for Tiger Crane integration, with reinforced subframes and pre-mounted crane pads
- Oilfield and pipeline proven — STI trucks work in the Eagle Ford, Permian Basin, and Gulf Coast every day
- Lube and fuel service specialization — Few brands match STI’s depth in crane body + lube truck configurations
STI Considerations
- Higher price point than entry-level service bodies (reflects heavy-duty construction)
- Best suited for chassis cabs (F-450+, Ram 4500+) — not a great fit for 3/4-ton pickups
- Longer lead times during peak season (Texas oilfield demand can run inventory thin)
Maintainer Service Truck Bodies: Ag and Utility Fleet Favorite
Maintainer (Shelby, IA) has been building heavy-duty service and mechanics truck bodies for over 60 years. They’re particularly well-regarded in agricultural mechanics applications — think large equipment dealerships, county road crews, and utility fleets that need robust, reliable service trucks. Maintainer has built a loyal following in the Midwest and parts of the South.
Maintainer Strengths
- Long track record — 60+ years of mechanics truck manufacturing, strong reputation with ag equipment dealers
- Mechanics truck depth — Maintainer’s mechanics body configurations are extensive, with numerous crane size options and compartment layouts
- Heavy chassis support — Maintains options up through F-750 and medium-duty Class 6–7 trucks
- Lube service bodies — Available lube service body configurations for oil change and fluid maintenance operations
Maintainer Considerations
- Dealer network in South Texas and Louisiana is more limited vs STI
- Higher price point — Maintainer trucks typically run on the premium end of the service body market
- Lead times can be significant; popular configurations sell out quickly
- Not stocked locally in the Wharton/Houston corridor — requires special order
Which Should You Choose?
Choose STI If You:
- Are in the Texas or Louisiana oilfield, pipeline, or Gulf Coast construction market
- Need a crane body + Tiger Crane combo build (STI is the preferred pairing)
- Want a local dealer who can spec, install, and service your truck in South Texas
- Need a lube truck or fuel service body alongside service body options
- Are outfitting a chassis cab (F-450, F-550, Ram 4500/5500)
Consider Maintainer If You:
- Run a large agricultural equipment dealership and have existing Maintainer relationships
- Need very heavy-duty medium-duty Class 6–7 chassis configurations
- Operate primarily in the Midwest or have access to a Maintainer dealer
