>>2794088>>2794087Yes. That specific model/brand you posted has a handful of safety features that will prevent you from killing yourself with either CO or burning the tent down by tipping it over as it automatically shuts off.
However I would still recommend a small fireproof mat to put under, in case you accidentally tip it so that you don't burn a hole through your tent floor (if a floor present).
One thing that you should keep in mind is that propane heaters, even that small one, put out a stupid amount of moisture. Your tent needs to be well ventilated while it is on, or everything will get absolutely soaked with the condensation.
>>2794099A few implies more than 2. Did you really fit 4+ people in a tepee tent with a stove too? Must've been really really close friends lol.
