Trailer Repair & Maintenance

RT Group's trailer repair shop in Zion, IL fixes dry vans, reefers, and flatbeds — frames, floors, doors, lighting/electrical, ABS, air systems, and structural welding — with drop-and-hook available on-site.

Trailer Repair Built Around Fleet Uptime

Trailers take a different kind of abuse than tractors — dock damage, cracked floors, worn door tracks, ABS faults, and electrical issues in lighting circuits that run the length of the unit. Our techs handle all of it in dedicated trailer bays sized for full-length dry vans, reefers, and flatbeds.

Trailer Services We Provide

  • Frame repair and structural welding
  • Floor replacement and repair
  • Roll-up and swing door repair and track replacement
  • Lighting circuit and wiring harness repair
  • ABS system diagnostics and repair
  • Air system repair (brakes, suspension, door seals)

Because RT Group owns the yard the shop sits on, drivers can drop a trailer for repair and hook to another unit without losing a shift waiting on it. We're a straight shot for owner-operators looking for truck repair near US-41 (Skokie Highway) to avoid Tri-State tolls, as well as fleets coming off I-94.
