Comprehensive Mobile Services for Diesel Semi-Trucks, Fleets, and RVs
California Mobile Fleet provides a complete rage of mobile diesel repair, emergency roadside assistance, towing, compliance, and maintenance services for commercial trucks, fleets, and RVs throughout Southern California.
Based in Calimesa, CA, our mobile service operation is built around one goal: reducing downtime and keeping vehicles compliant safe, and on the road. Instead of forcing trucks and RVs into a repair shop and losing valuable time, we bring professional tools, advanced diagnostics, and experienced technicians directly to your location.
From emergency breakdowns to scheduled maintenance and compliance inspections, our services are designed to support both immediate needs and long term fleet reliability.
Emergency Mobile Diesel Repair and Roadside Assistance
Breakdowns can happen anywhere and at any time. California Mobile Fleet specializes in emergency mobile diesel repair and roadside assistance for semi-trucks, big rigs, fleet vehicles, and RVs.
Our technicians respond quickly to diagnose issues on-site and perform repairs whenever possible, helping drivers avoid unnecessary towing and extended downtime. Emergency roadside service commonly includes no-start conditions, engine derates, electrical faults, sensor failures, cooling system issues, fuel system problems and after-treatment system faults.
With
advanced diagnostic software and real-world diesel experience, we focus on accurate repairs that get vehicles safely back into service.
Mobile Diesel Mechanic Services for Semi-Trucks and Big Rigs
Our mobile diesel mechanic services are designed specifically for Class 7 and Class 8 trucks, including highway tractors, regional haul trucks, vocational vehicles, and commercial fleets. By bringing the repair facility directly to the truck, we eliminate delays associated with shop scheduling and towing whenever possible.
Mobile diesel repair services
include engine diagnostics, component replacement, electrical troubleshooting, cooling system repairs, and fuel system diagnostics. These services are ideal for fleet yards, job sites, terminals, and roadside locations throughout the Inland Empire, High Desert, Coachella Valley and surrounding regions.
Advanced Diesel Diagnostics and Computer Software Services
Modern diesel engines rely on complex electronic systems that require specialized diagnostic equipment. California Mobile Fleet utilizes manufacturer level diagnostics software to quickly identify faults and reduce guesswork.
We provide
diesel diagnostic and repair support for major diesel engine platforms including Cummins, Detroit Diesel, Volvo, Mack, International, PACCAR, Hino and Isuzu. Transmission diagnostics and support are also available for Allison and Eaton systems.
Accurate diagnostics
lead to faster repairs, lower operating costs, and improved reliability, especially for fleets operating multiple trucks.
Diesel After-Treatment and Emissions System Repair
After-treatment system failures are one of the leading causes of truck derates and shutdowns in California. Our mobile diesel services include after-treatment diagnostics and repair to address issues related to DPF systems, DEF systems, sensors and emissions components.
By
resolving emissions-related problems early, we help prevent extended downtime, costly component damage, and compliance issues. These services are especially critical for trucks operating regularly throughout California’s regulated emissions environment.
CARB Clean Truck Check and DOT Inspections Services
Compliance is a critical part of operating commercial vehicles in California. California Mobile Fleet provides CARB compliance Clean Truck Check inspections to help fleets and owner operators meet California Air Resources Board requirements.
In addition, we offer DOT inspection services to help identify safety concerns before they result in violations, fines, or out of service orders. These inspections support both preventive maintenance planning and fleet compliance programs, giving operators confidence that their vehicles meet required standards.
Preventive Maintenance Services for Fleets and Owner Operators
Preventive maintenance is one of the most effective ways to reduce breakdowns and extend vehicle life. California Mobile Fleet offers mobile preventive maintenance services designed to keep trucks and RVs operating reliably.
Preventive maintenance services support early detection of wear, fluid issues, component failures, and compliance concerns. This proactive approach helps fleet managers reduce emergency repairs, improve scheduling reliability and control long term operating costs.
Fleet Diesel Repair and Maintenance Programs
Fleet operations require consistency, documentation, and dependable service. California Mobile Fleet works closely with fleet managers and trucking companies to provide scalable fleet diesel repair and maintenance services tailored to operational demands.
Fleet services
support emergency response, scheduled maintenance, compliance tracking, and multi-unit service coordination. Whether managing a local fleet or operating across Southern California, our team helps reduce downtime and keep vehicles compliant and road ready.
Trailer Repair and Mobile Trailer Services
Trailers are a critical part of fleet operations, and trailer issues can quickly disrupt schedules. California Mobile Fleet provides mobile trailer repair services to address common mechanical and structural concerns.
Trailer repair services support fleet safety, cargo protection, and DOT compliance. By servicing trailers on site, fleets can avoid delays associated with shop drop offs and scheduling conflicts.
Semi-Truck, Heavy-Duty and RV Towing Services
When on-site repair is not possible, California Mobile Fleet offers heavy-duty towing services for semi-trucks, big rigs, trailers, and RVs. Our towing operations focus on safe handling, proper equipment use, and efficient transport.
Towing services are available throughout the Inland Empire, Riverside County, Orange County, Coachella Valley, Greater Palm Springs region and the surrounding areas.
RV Repair, Maintenance and Towing Services
In addition to commercial trucking services, California Mobile Fleet provides mobile RV repair, maintenance, and towing for RVs and motorhomes. RV services are ideal for travelers, seasonal residents, and fleet operated recreational vehicles.
Mobile RV services include diagnostics, electrical troubleshooting, cooling system repairs, after-treatment diagnostics, and preventive maintenance. When roadside repair is not possible, we coordinate safe
RV towing using our heavy-duty equipment.
