The pin is Crescent City, not an address. David's Mobile RV Service works from a vehicle and comes to you.
David's Mobile RV Service is a mobile RV tech serving the Crescent City, California area. It comes to you, at your local park, and there is no travel fee for local parks, though a scaled travel fee may apply beyond the Crescent City area.
David Nanney works on heating and cooling systems, furnaces, air conditioners, water heaters, RV electrical systems, converters and inverters, slide-outs, awnings, appliances, fresh water systems, stabilizer jacks and leveling systems, and black water tank issues, on brands including Dometic, Suburban, Atwood, Coleman, Duo Therm, Carrier, Parallax, Xantrex, Lippert (LCI), Schwintek, Norcold, Thetford and others. He calls himself "an insured RVSA-certified master RV technician," a certification worth asking about when you call, since it signals training specific to RV systems rather than general handyman work.
The service fee is $120 to come to you, diagnose the issue and discuss repair options, and that fee includes a free roof inspection on request. The hourly rate is not published, so ask for it when you call. He sometimes works with manufacturer and third-party warranty companies, but payment is typically collected from you directly, with a detailed receipt provided for you to submit for reimbursement. Someone answers the phone Monday through Friday from 10am to 6pm, and he returns messages as soon as possible.
Google rates him 4.8 stars from 13 reviews.
This is a good fit for an owner near Crescent City who wants a tech to come to the campsite rather than haul the rig somewhere, especially for electrical trouble or a roof check while he is already there.
