about perfect for a 30 amp RV!

I wrote "Most of you are thinking of a so-called autoformer that automatically changes output voltage as the input voltage changes."

I said so-called because on the forum most think of a autoformer as a Hughes or Frank's autoformer.

From Hughes:
Unlike a boost transformer, the ‘sense circuit’ in the Autoformer will adjust the output based on the load demand.

Hughes Autoformer

So I went to your link and found incorrect information right there. For example: How can one get 3600 watts of 120 volt power thru a 30 amp breaker operating at 100 volts?

From the website:

Hughes Autoformers are designed to increase voltage to your RV and help eliminate low voltage damage to your appliances. Unlike a boost transformer, the ‘sense circuit’ in the Autoformer will adjust the output based on the load demand. For this reason you can run additional appliances on a 30-amp input. For example, a coffee pot and microwave each draw 1200 watts. Add wattage for the converter and/or a refrigerator – about 800 additional watts – and now you have 3200 watt demand. If you are only getting 100 volts from the supply, the maximum wattage would be 3000 watts. In this case, the Hughes Autoformer will boost voltage to give you 3600 watts to your RV!
