Trusted by Drivers and Fleet Managers
Our customers rely on us when it matters most—during roadside breakdowns, before major hauls, and when critical fleet units go down. San Antonio has plenty of 18-wheeler diesel shops and mechanics, but few offer a full stack of services including tractor and trailer shop repairs, mobile roadside services, heavy duty 24-hour towing, and trailer work under one roof. Texas Truck & Trailer Repair is built for working trucks and trailers that can’t afford long, extended downtime.

Truck & Trailer Repair FAQs
A few of the questions we hear most often from drivers and fleet managers.
Do you offer mobile diesel repair or only in‑shop service?
We offer both. For many issues, we can dispatch a mobile diesel technician to your truck in the Converse and San Antonio area. When a repair is too large or unsafe to complete roadside, we coordinate towing and finish the work in our shop.
What types of trucks and trailers do you work on?
We service most heavy‑duty diesel trucks, semi‑trucks, vocational trucks, and a wide range of trailers—including dry van, flatbed, utility, and equipment trailers—as well as many RVs, buses, and diesel‑powered equipment.
How fast can you usually get me in?
Scheduling depends on workload and the type of repair, but we prioritize downed trucks and urgent fleet units. For many services, we can offer same‑day or next‑available appointments—call to discuss your situation.
What areas do you serve for roadside assistance?
Our roadside service focuses on San Antonio and surrounding highways and industrial areas. Call with your current location and we’ll confirm coverage and ETA.
