Our "classic" coach came with King pic a watt heaters which are still available on Amazon . They are 120 volt , with heater element taps . You have a choice to make it a  250, 500, 750, 1000, 1200, or 1500 watt heater at 120 volts at time of installation . Very quiet. We have replaced most of our over the years. Our use remote wall thermostats, but I suppose your application could use a thermostat on the enclosure. The part numbers I have provided are for white, but almond is also available.

If you call king, they are very helpful
