RE: stoves
Elkkrazy.....
you get metal hot enough (stove), some warping will take place. Now if it's made out of thick metal, it will resist it better than thin metal. But if you are like most and only use it for a short period of time per year, you will make the call on whether it is of "value" for you to invest the extra money to get one that doesn't warp.
As for the condensation, all things being equal, the propane does put moisture back in the air, but if you vent it properly it will be minimal. Wood burning stoves actually pull moisture out of the air during the process. Either way, the beauty of the canvas tent is it's ability to "breathe"!!!!
I can tell you from personal experience, you can burn propane (Dearborn stove turned up with the flames coming out the front vents) all night long in a completely sealed tent (non-canvas, non-breathing) and live to tell about it. But let me assure you that if you have CO detecters in the tent, they will be going off after a couple of hours and you will have a headache and you will realize how stupid you were and that you are lucky to have not killed someone!!!!!! (Yup...been there, done that!)
