Inverter,,yes or no??

I see that you changed it to "Inverter".
Questions to decide would be,,,
1 What do you want to use it for?
Is there something that you currently cant do that the inverter would provide for?
2 Is it to minimize generator needs?

Remember that to run an inverter you will be draining batteries, do you have a method to recharge other than your genny?

You need some method of charging the batteries.

Best is a smart charger
Second best smart converter
Third "stupid" converter

Since I suspect your coach came with one, assume someone removed it???
