Advanced Mobile Automotive Services

Advanced Mobile Automotive Services is an RV repair shop based in Diamond Springs, California. The listing does not say whether it comes to your campsite or driveway, or whether you bring the rig to its own location, so ask when you call.

There is no website, so no trip fee, hourly rate or list of what systems it handles is published anywhere. Ask up front what it works on, what a service call costs, and whether that includes diagnosis or just the drive out.

Google rates it 3.8 stars from 10 reviews.

This is a good fit for a traveler or owner near Diamond Springs willing to call first and get the basics (trip fee, service area, and what it actually repairs) before booking anything.
