I have a Yamaha 2000 and used it last weekend. But I realized how painful it is to hook up heaters, pumps to two different tanks. And I still didn’t have any power in the rest of the house. It was getting cold too and the heaters had trouble keeping up
so I just ordered a champion 7000 inverter generator from Home Depot. This should run the whole house. I just made a suicide cord for the dryer plug. Don’t judge me
switch panels don’t run the whole house, only the circuits you decided to hook up to it
