So it sounds like there is no way to directly make our house batteries run the RV's AC plugs. Darn.
You make a good point that one would not want to run those down or could cause a problem starting the Generator later.
I have ordered a simple inverter to plug into the chassis battery as well as a "laptop auto adapter" ....but they say you would need to run the RV engine in order to avoid draining the chassis battery.
Has anyone used these Goal Zero products?
This line of devices appears to have its own battery and inverter. It can be charged up by 12V battery(cigarette lighter), shore power, or solar panels. Sounds like it may be a practical solution (although not inexpensive).
