I used a 16x20 for a short while but finally went to a 12x14x5 as it was easier to pack on a horse and easier to set up. I used a stove I built from a 55 gallon barrel cut in half with a SS top to cook on if need be, it also had a built in oven....It uses a good bit of wood btw, but it will run you out of any tent, no matter how cold, if you really stoke it up...I also had a 3 burner grill running off a butane bottle for most cooking.
For what its worth I always took a 5 gallon can to mix sawdust and Kerosene for a fire starter..It's safe and fast on a cold Idaho mountain morning.
