These units work great for heating up a tent without the risk of carbon monoxide since the heat unit sits outside of the tent and hot air is blown into the tent through the vent system. You will need to hook it up to a 12v battery and propane. I have two available, one has a stand and is lightly used (the one with the ZODI hot camp shower bag behind it), and the other is new but doesn't have a stand. Asking $150 for each of them + shipping, OBO.
