Hey Chris, thanks for reaching out. Yes, you can use the Cummins Onan P4500i 4,500-Watt Inverter Generator # CM76MR to power your 50-amp RV with a 30-amp-to-50-amp dogbone adapter. The generator has a 30-amp RV outlet, so you'll just need an adapter that connects the generator's 30-amp outlet to your RV's 50-amp power cord.

The important thing to remember is that the adapter doesn't increase the generator's power output. You'll be limited to the generator's available wattage, so you'll need to manage your electrical usage, especially when running appliances like air conditioners, microwaves, and water heaters.

Are you primarily looking to run your air conditioner, or just keep the lights, outlets, and other basic appliances powered while camping?
