Pro Line Diesel & RV Repair

Pro Line Diesel & RV Repair is a mobile diesel and RV repair business based in Valencia, California. It comes to you, at a campsite, a storage facility, or your own driveway, so a dead Class A does not need to be towed anywhere.

It works on Class A and Class C motorhomes and diesel pushers, covering chassis, drivetrain, generator service, electrical troubleshooting, slide-out system diagnosis, cooling and HVAC, and pre-trip inspection and safety checks. It names Newmar, Tiffin, Entegra, Fleetwood, Monaco, Holiday Rambler, Coach House and American Coach among the brands it services. Its service area covers Valencia, Santa Clarita, Newhall, Saugus, Canyon Country, Stevenson Ranch, Castaic and Acton.

No trip fee, hourly rate or diagnostic fee is published, so ask about the trip fee when you call. It advertises being "Available 24/7 for emergency diagnostics and repairs," which matters if a generator or slide-out quits on a weekend at a campground far from any shop.

The technician named is Jay, who one reviewer says "took the time to explain in detail what was wrong with my truck" and offered recommendations "without making me feel rushed." The company describes bringing "dealership-grade diagnostic equipment," worth asking about directly, since a lot of mobile outfits carry little more than a basic code reader for the complex electrical and chassis systems on a diesel pusher.

Google rates it 4.6 stars from 129 reviews.

This is a good fit for a diesel pusher or Class A owner around Santa Clarita who needs a tech to come to the rig rather than move it, and who wants a clear explanation of the problem before any work starts.
