I agree that conditions on occasion requires this setting. For example if it is extremely cold and you need all the heat or cooling possible. Sort of like using a ten pound hammer to drive finishing nails. It will work, but not so well.
For both A/C and heating, it is always best to use an output that is just more capable than the load. This alone will give the best comfort as the machine is cycling much less. Less cycling gives more even temperatures.
So, I suggest turning the unit on to high to warm or cool the area, and then using a lower setting for the evening. If the unit can't keep up, then go back to the high setting.
That said, trailer and unit limitations are different for each of us. If my recommendation does not work for you, then see the above responses and spend some more money.
The control knob on almost all ceramic heaters is really a thermostat, and they are typically not very accurate. If they are dual wattage ceramic heaters, say 900w or 1500w, when on that is what their output is. The control knob does NOT raise or lower the heat output. When I posted to put it on high when using a remote control thermostat, I meant turn the heaters thermostat to high so that it will not override the remote control thermostat, which will turn the heater on and off at a set temperature, and do so far more accurately than the “built-in” thermostat. Every time I thought I had found the “sweet spot” and marked the dial, the next time I used the heater it would either come on at a lower or a higher temperature.
