For folks that can be bothered with diodes, a simple solution is a marine grade key starter switch that like a car that has an ACC terminal.

Simply power a 200A cont duty relay (about $40) from the ACC terminal .

This is how its done on millions of RV for a half century , though most use a 60-75A solenoid for $18. or so.
