You are in a small meltable back packing tent, perhaps a stable candle job would be all that would be need to take a bit of chill and humidity out of the air. We have used one on early season canoe trips, they are safest if hung and not on the floor of the tent. With bigger canvas tents, the three dogs are safe with the charcoals and kids. With the big nylon domes and in a campground situation, a flame proof rug and an electric heater is really convenient and safe, but of course a stout extension cord and a place to plug it in is a big help.
