Shops that know RV electrical
Fontana has three shops that list electrical repair, and two of them also send mobile techs. J & L RV Repair is the biggest name here with 86 reviews and a 4.5 rating. They also handle roof, fridge, awning, slide-out, and body work, and they do warranty and insurance jobs. Fleet Services Group is another mobile option, with a 4.3 rating, and they cover A/C, tires, and chassis too. RV & Motorhome Repair Center rounds out the three, with a 4.0 rating, and they work on generators and chassis as well. For electrical, all three can help, but call ahead to see if they have the part in stock.
Mobile techs versus shop time
Two of the three Fontana shops offer mobile service, which can save you a tow if the problem is a dead battery or a faulty converter. Mobile techs come to your site or driveway, but they may not have every part on the truck. If your rig needs a deep electrical diagnostic, a shop with a dedicated bay might be faster in the long run. Ask about diagnostic fees and whether they stock common parts like fuses, relays, and converters. Also, if you're under warranty, get pre-approval before any work starts.
What to check before you call
Before you call a shop, do a quick check of your own. Look at the breaker panel and the GFCI outlets. Sometimes a tripped GFCI is the whole problem. Check your battery connections for corrosion and make sure the disconnect switch is on. If you have a generator, see if it runs and whether the transfer switch clicks. Write down what works and what doesn't, including which outlets are dead. That saves the tech time and you money. Also, note your RV's year and model, since electrical systems vary a lot.
