On Board RV Generators

An on board generator is built directly into your RV, providing a dedicated and convenient power source without the need to store, transport, or set up a separate portable unit. For full-timers, frequent dry campers, or anyone who relies heavily on appliances and climate control away from hookups, an on board generator is a practical long-term solution.

Whether you are replacing a failed factory-installed unit or adding a generator to an RV that was pre-wired for one, selecting the correct model matters. Output wattage, fuel type, and physical dimensions all need to align with your RV's existing setup. Check your RV's generator compartment dimensions and power requirements before ordering to confirm the correct fit for your installation.
