Cracker You put a little wood stove in there and you will be opening the flap a little to be able to stay inside. I've stoked mine up at -10 F and had to crack the flap. I think one of them little top loading trash burners would serve you well and they don't cost a helluva lot. I floor mine with a poly tarp and just take it out and shake it when it gets dirty, (don't have to sweep it) I got my last wall tent from Cabela's (If I remember right) back in 1987. Still going strong. Make sure when you store it that the mice can't get to it, (They like to chew smoky canvas) If you got long leaf pine where you are,you could'nt get better poles. My 12x14 uses nine fifteen footers (Mine are lodgepole pine) skin the bark off them,get them smooth and let them dry for several months. Another 2 cents ' Frank
