- Very positive customer reviews
- 3 years limited residential and 270 days limited commercial warranties
- A lot of customers
Cons
- Noise levels of 72 dBA can be too loud for the RV park or camping guidelines
- Run time is not the most impressive
The run time of 10.5 hours is also not the greatest although 25% of 7250 running watts is a lot more than what the other RV inverter generators offer.
While you do want to know about these downsides, the Champion 201067 9000 is still one of the best 50 amp inverter generators for good reasons.

FAQ
What is better for an RV a regular generator or an inverter generator?
Since you will very likely run at least some sensitive electronics inside your RV, inverter generators tend to be the better choice.
These allow you to prevent damage that would be more costly than the small extra investment in an inverter.
What size inverter generator do I need for my RV?
What size inverter generator you need for your RV will mainly depend on how big your air conditioning is and its specific power requirements.
For example, an 11k BTU RV air conditioner often needs around 1600 starting watts but potentially more than that. Especially if you want a safety margin.
After this initial burst of power, the generator often has enough running watts left for small devices like a TV or phone charger.
To run medium-sized devices like a refrigerator, microwave, toaster, or coffee maker together with your AC, you typically want a 3000+ peak watt inverter generator for your RV.
Do you need an inverter generator for an RV?
Since many of the devices you would typically run in an RV are sensitive electronics, you generally need an inverter generator for this.
