500: 220v AC interior splitter

[garrybry]

I am caretaking a LAGOON 500 and I want to take an interior 220v socket and plug in an adapter to make two plugs. Then I need an adapter to take it to US ac socket as well. I need to run the washer and a printer. The printer has a select to accept 220 VAC. Any tips on locating them?
