Well,
I'll be the different one. Our coach, an '04 Itasca Horizon, 36GD with the CAT C-7 330HP has an Inverter/Charger. It was a Dimensions 2000 Watt unit but, after 11 years, the charging side gave up the ghost. So, we purchased a Magnum ME2012. It's the same specs, an Inverter/Charger, 2000 watt. It powers up, every single outlet in the coach.
But, we NEVER have it or turn it on, unless we need it. I guess we're just not the worrying types. If the power goes out, we'll figure it out when the time comes. If, we're watching TV and using the Genny, which means the Inverter is off, we'll turn it on and shut down the Genny. When we're done watching what we want or, are tired and want to go to bed, off goes the TV and the inverter.
We've been doing it that way, for almost 8 years since we purchased it. So far, we've not had one single issue operating this way. By the way, if the batteries are turned off, the charging side of that inverter still charges the house AND the chassis batteries.
