Join CTOS as a Mobile Expert in Utility Fleet Repair
Sun up on the Gulf Coast. Your phone buzzes with a dispatch to a customer yard where a bucket truck is sidelined with a hydraulic leak. You arrive in your fully equipped service truck — crane, welder, and compressor on board — and get to work. A quick diagnosis, a hose swap, and you’re on to DOT and dielectric checks before rolling to the next site. That’s a day in the life of a Field Service Mechanic at Custom Truck One Source (CTOS).
