California Coast Truck Repair

California Coast Truck Repair is a diesel repair shop based in Santee, California. You bring the RV to its shop at 11366 North Woodside Ave; it is not a mobile operation, so plan on driving in rather than waiting for a tech to come to you.

It focuses exclusively on 2006 and newer diesel trucks, diesel RVs, and motorhomes, and serves owners from across San Diego County, with the shop a convenient stop near I-8, I-15, I-5, and I-805. On the RV side, the work covers cooling systems, brakes, electrical, and pre-trip checks, along with diagnostics, transmission repair, brake service, emissions-related repairs, oil changes, and engine replacements. That focus on diesel only, rather than a shop that works on everything with wheels, usually means fewer comebacks on a complex Cummins-powered rig.

There is no published hourly rate or trip fee, so ask about cost when you call. The shop does offer after-hours drop-off if you cannot get the RV there during open hours, which run Monday through Friday, 8 AM to 5 PM. It also offers financing through CB Charge and Synchrony if a bigger repair comes up unplanned.

Technicians are ASE-certified and Cummins-certified, and the shop is an ASCCA member and a NAPA Truck Care Facility. Work comes with a 12-Month/12k-Mile warranty on parts and labor, which matters if a repair fails down the road and you are not local anymore. Google rates it 4.8 stars from 71 reviews.

This is a good fit for an owner of a diesel motorhome or RV who wants a shop that only works on diesel, not a generalist, and who can get the rig to Santee or is already passing through San Diego County on I-8 or I-15.
