KING 1000 watt portable baseboard heater in the Truck Camper

My TC just does not need a 3 or 4 foot heater with a 1000 watts. Even in the coldest weather my 600 watt unit is way more than I need to maintain 70 degree heat in below freezing weather. If you need a big heater to maintain comfort at 45 degrees you might want to check for air leaks and areas where the insulation could be improved. I have sealed the wheel well areas and added a carpet. Both made large improvements in the warm and comfort.
