I used a ceramic heater this week while camping and I'm still alive
I have 2 heater. A small one for the bedroom and larger one that sits in between the front seats on the dog house
Temps dropped down to the low 50s high 40s. We ended up turning off the bedroom heater. The big one heated the entire mh
Both of mine will shut off if it tips over. This was the first trip using them and not the furnace. I was very happy with them
