KING 1000 watt portable baseboard heater in the Truck Camper

I am also concerned about the amount of space needed. Space heaters are not all that safe and I would only feel comfortable with a large space around the unit. I also bought my space heater at Lowe's. It has a pretty quiet fan, 2 levels of heat, a tip over safety and a thermostat. It was about $15-20. Mostly mine is small and I found a relatively safe place for it. The lowest setting is 600 watts. I have never needed the high setting. I use it to keep my TC just above freezing during the winter months of storage.
