Rob,
What may be confusing is how little power you can extract from a lead acid battery for doing anything but starting your GMC. It is a very inefficient way to power any 120vac device no matter how efficient or inefficient the inverter. And lead acid batteries take a long time to recharge no matter the capacity of the charger.
You can downloads presentation I did ten years ago called “Living large in your GMC” to see the best you can achieve with lead acid batteries and, after the new presentation is given at GMCWS in Oct, you will be able to download that one to see how very far we have come in just ten years.
