Truck down in St. Louis?

St. Louis sits on I-44, I-55, I-64, I-70 — freight that can't wait for a tow to a shop. Mobile diesel mechanics come to the truck: roadside tire service, air brakes, electrical and starting problems, cooling systems, DPF and regen issues, and trailer repair, at the truck stop, the receiver, or the shoulder.

Every shop on this page is dispatchable through RIG — one call or chat sends your breakdown to the closest available mechanics, who bid back by text with exact price and ETA. You pick, they roll, and payment settles only when the work is done. That marketplace model is why RIG is how drivers get moving in St. Louis: no phone-book roulette at 2am, no blank-check invoices.
