RV Generator Installation in Chino

The short answer

OCRV Center installs new and replacement generators in RVs and specialty vehicles at our Yorba Linda shop, handling the mount, fuel supply, exhaust routing, and transfer wiring to code. We size the set to your real electrical load so it actually carries your A/C and appliances.

Ballpark: $400 to $8,500+

Installing a generator is more than bolting a box into the bay. The set has to be mounted to handle vibration, plumbed into the correct fuel source, exhausted safely away from the cabin, and wired through a transfer switch so it does not back-feed shore power. We do the full installation in shop so every connection is built and tested correctly. All work is in-shop only at our Yorba Linda facility.

Sizing the generator to your coach

The first job in any install is matching the generator output to the load it has to carry. An undersized set will surge or stall when the air conditioner cycles on, and an oversized one wastes fuel and money. We add up your A/C units, the microwave, the converter or inverter charger, and the rest of the loads, then specify a set with the headroom to start the A/C compressor without browning out the coach.

  • Load calculation across A/C, appliances, and charging
  • Gas, diesel, or LP set matched to your fuel source
  • Onan and Cummins models for RVs and fleet vehicles
  • Output sized to start the A/C compressor cleanly

Mounting, fuel, and exhaust done to code

A generator install lives or dies on the details that nobody sees. We build the mount to isolate vibration so the set does not crack its own welds or shake the bay apart, tie the fuel supply into the correct tank pickup or LP line, and route the exhaust to discharge safely away from windows, doors, and the cabin. Sealing and clearance around a hot exhaust is a safety item, not a finishing touch.

  • Vibration-isolated mount built into the generator bay
  • Fuel supply tied to the proper tank pickup or LP line
  • Exhaust routed clear of windows, doors, and the cabin
  • Heat shielding and clearance around the exhaust path

Transfer switch and start wiring

The electrical side is where a sloppy install becomes dangerous. The generator has to feed the coach through a transfer switch so it can never back-feed onto the shore-power cord, and the remote start and panel monitoring have to land on the right terminals. We wire the transfer switch, the start circuit, and the panel gauges, then run the set under load to confirm it starts, transfers, carries the A/C, and shuts down clean before the rig leaves the shop.

Questions

Frequently asked questions

How do I know what size generator my RV needs?+

We calculate it. We total your A/C units, microwave, converter or inverter charger, and other loads, then size a set with enough headroom to start the air conditioner without browning out the coach. Guessing on size is the usual reason a new generator surges or stalls.

Can you install a generator and the transfer switch together?+

Yes. A proper install includes wiring the set through a transfer switch so it cannot back-feed your shore-power cord, plus the remote start and panel monitoring. We build the mount, fuel, exhaust, and wiring as one job and load test it before it leaves.

Is generator installation done in shop?+

In-shop only. Bring your rig to our Yorba Linda facility at 23281 La Palma Ave and we will handle the mount, fuel, exhaust, and transfer wiring and test the set under load there.
