the night temps were mid teens to about 30.the highs were low 30s to low 40s.if you are camping much colder than that,get the big buddy heater.it runs at 18000 btu on high and has a fan that can use d batteries.the batteries are expensive to bring a weeks worth,but i think it would be worth it.i had some cold spots in my tent and am researching battery powered fans to distribute the heat better.i also had a 10x10 easy-up canopy with side walls that i used to cook in,but on the colder days,it was too cold for me to sit around in.the side walls block some of the wind,but not all of it.i used a 17x17 square of ceramic tile flooring that i bought at lowes to set the heater on.something else i will get is a small cheapie throw rug to put on the tent floor.the idea of a wood burning stove doesnt sound bad,but ive never seen a tent with one in it myself.
