About S-O-D LLC
S-O-D LLC is a mobile diesel repair and preventive maintenance service built for fleet operators, owner-operators, and heavy equipment owners across the San Antonio and Austin regions. Instead of towing your truck to a bay and losing billable hours, our rapid-response service brings the shop to your equipment — wherever it's down, whenever it's down. Our service radius includes, but is not limited to, San Antonio, Austin, New Braunfels, and the Seguin / Schertz corridor, with 24/7 dispatch.
For the operations whose excavator quit mid shift. From full top-end service and heavy-duty tear downs to hydraulic systems repair, DPF and emissions work, and on-site major component swaps, we diagnose accurately and deliver the exact solution needed to return your equipment to peak performance. Speed and precision are our absolute priorities, because minor issues become catastrophic failures when they're left to wait.
S-O-D LLC is owned and operated by Rob Rodriguez, a diesel technician with over a decade of field experience. Rob built this business on a simple principle: the right tools, the right diagnosis, and a fast response save customers money and keep their fleets earning. Every inquiry submitted through this site is reviewed personally and answered within 24 hours.
