Brian's Automotive Repair is a full-service automotive repair shop based in Ontario, California. It is a shop you bring the RV to, not a mobile outfit, and it says plainly, "We perform complete RV services and repairs."

It works on motor homes and trailers, covering generator service and repair, roof inspection and repairs, plumbing and electrical repair, wheel bearing packs on trailers, and general trailer maintenance and repairs. It also notes that it performs regulator oil service on motor homes. No service area is published, so if you are coming from outside Ontario, ask how far a drive is reasonable or confirm your rig can be driven in.

No trip fee, hourly rate or diagnostic fee is published, so ask about those when you call. It does offer financing through Synchrony Car Care, which can help if a repair bill runs higher than expected.

Brian's backs its work with a warranty for AAA members, "1 year/12k mile & 2 year/24k mile warranties," which matters if a repair fails down the road and you want it covered without a new bill. It has been serving Ontario for years. Shop hours are Monday through Friday, 8am to 5pm, closed weekends.

Google rates it 4.7 stars from 184 reviews.

This is a good fit for an RV owner near Ontario who can bring a motor home or trailer in during weekday hours and wants a shop that handles both general auto repair and RV systems like the generator, roof and plumbing under one roof.
