No issues, ran everything except 2 ACs in the RV, which is to be expected. It will run all night on a tank of gas. It's quiet and does what it's supposed to do. It's heavy no doubt. I have to have help to lift it into an RV compartment, but it does have beefy handles.
This replaces another brand 6500 watt low thd generator. This inverter is so much quieter and provides all the power I need to run the whole house necessities like the gas furnace and water heater the refrigerator and the freezer with enough left over to watch a lcd tv and a couple of lights.
