Dave,
Okay, now I get it. You have six batteries, two house and 4 for the inverter. That is why you have an Inverter and a converter.
Really had me confused. I only have 4-6 volt batteries that run the inverter and also used for the house 12 volt systems.
I also have 2-12 starting batteries for engine.
I am no longer confused.
Yep, traveling and using the coach sounds like the best plan.
