I have one of them. I can only use it when there is no GFI breaker on the 15 amp side of the power box. If there is a GFI on the box it always trips because of the GFI circuit in the rig. You can't have two GFI circuits hooked together. We only use it when volunteering at a State Park in Washington and we have to be careful about overloading the breaker.

You might get by with it if it is an old style non GFI circuit but make sure the fridge and water heater are on gas before trying both AC units on the power pedestal.
