Rapid Diesel Repair

Rapid Diesel Repair is a diesel truck and fleet repair shop based in Ontario, California, at 251 Kettering Dr. You bring the RV to its shop for most jobs. It also lists mobile truck repair, roadside assistance and towing among its services, so ask when you call whether that reaches your motorhome or trailer where it sits.

The shop works on motorhomes under what it calls "RV, Trailer & Specialty Diesel Service," covering chassis and brake work on top of its broader diesel trade. That broader trade includes engine and drivetrain repair, diagnostics, emissions system work, suspension, steering, alignment, air brake and wheel-end repair, cooling and HVAC systems, fluid service, and transmission and clutch work, the same systems that sit under a diesel motorhome's hood and chassis. It names experience across Freightliner, Hino, International, Isuzu, Kenworth, Mack, Volvo, Western Star, Mitsubishi Fuso, Cummins, Detroit Diesel, PACCAR and Allison, among others, along with Ford, Chevrolet, GMC, Duramax and Ram.

No hours, pricing or trip fee are published, so ask about those along with the mobile radius when you call. The shop names Ontario, Rancho Cucamonga, Fontana, Riverside and San Bernardino as areas it serves. Its technicians are ASE certified, which means a diesel-specific credential rather than general auto training, worth something on a chassis that most RV dealers will not touch.

Google rates it 4.9 stars from 317 reviews.

This is a good fit for an owner of a diesel motorhome in the Inland Empire who needs chassis, engine or drivetrain work done at a shop built around diesel trucks rather than a general RV dealer.
