My old inverter is on its last legs and am getting a new Magnum. I think my current system has 3000 Watts. Can anyone explain how to think about the sizing? Should I upgrade to a larger unit? The old one ran everything except Aquahot and A/C on battery....So to my brain it was sufficient. But the new coaches have two inverters...I wonder why that is. Should I just replace the 3000 Watt ProSine with a single new 3000 Watt Magnum?

Cheers,
