Truck Repair Shop & Mobile Service in McKinney, TX
MTG Shops now has a full-service truck and trailer repair shop in McKinney at 3462 County Road 341, Suite 200 — bring your truck to us, or we'll roll a 24/7 mobile diesel mechanic to your roadside, fleet yard, dock, or jobsite along the US 75 corridor through McKinney, Plano, and Frisco. Diagnostics, brake and air repair, electrical, tires, and parts sourcing — most calls are fixed where the truck sits.
MTG Shops mobile service truck — dispatched to US 75 and SH 121 breakdowns across Collin County, TX.
// Why MTG serves McKinney
The US 75 corridor is where North Texas freight moves
McKinney sits on US 75 in Collin County — one of the fastest-growing freight and logistics corridors in the United States. Between DFW Airport and the Oklahoma border, US 75 carries semi trucks from the Plano and Frisco distribution centers north through McKinney to Sherman–Denison and beyond. The SH 121 tollway ties McKinney directly to DFW Airport and the Alliance corridor to the west.
MTG Shops is headquartered in Harlingen, TX, with fixed shops in Brush, CO, Green River, WY, and now McKinney, TX. We opened the McKinney shop at 3462 County Road 341, Suite 200 because the distribution-center density and US 75 truck traffic here generate the same breakdown volume we handle in our home markets. Our mobile units are deployed in the field across North Texas — backed by the McKinney shop's parts inventory, bays, and fleet account infrastructure.
If your truck is stopped on US 75 near Eldorado, broken down at a distribution center off SH 121, or sitting dead in a fleet yard in North Plano, we roll a mobile mechanic to you with the tools and parts to fix it on scene.
