RV repair in Ontario, California: mobile techs who come to you

2 mobile RV techs are based in Ontario, plus 2 repair shops you bring the RV to. 8 more techs are based in another town and serve Ontario too. They are listed under "Also serving Ontario." None publishes a rate, so ask on the phone what the trip fee is and whether it covers the first hour. 1 names a certification we can link to. Beyond repair, Ontario also lists 1 RV inspector.

Ordered by who is most likely to be able to help today: techs who come to you first, then whether they publish their rates, whether they take after-hours calls, their reviews, and how much they work on. Anyone who is only in town part of the year drops down while they are away. Sponsored listings sit at the top and are labelled. Data read 2026-10-22.

5 of the 5 techs here publish a street address, and those are the pins. The rest work from a vehicle and do not publish one, so they are on the list but not on the map. The small round dots are other listed techs and shops nearby (a hollow dot is a town whose mobile techs publish no address). Tap one to open it, or zoom out for more.
