i just got back from a week of camping/hunting.ive got a tent that is very similar to cabelas alaskan guide tent.my tent is hexagon 10x13.i heated it with the smaller buddy heater.got about 90 hrs of use from a 20lb propane bottle.didnt have any condensation at all.but my tent is essentialy a double walled tent with the full coverage fly.im going to add a small battery powered fan to distribute the heat better.2 things to consider,if you go by yourself,get a tent you can easily put up alone.mine is doable,but a pain.get a tent larger than you think you need.on days when its too cold to sit around or cook,and your confined to the tent you will be glad you got a larger one.if you will have electric,by all means use electric appliances.some guys in a huge brand new pop up camped by me.they had a furnace in it and a small honda generator(very quiet)to power the lights and furnace blower fan.i cant say i wasnt envious.
