In a tent style icehouse that a breathable MR. Buddies work great, in a ridged they produce a lot of moisture during combustion and you get condensation all over the walls even the ceilings start to drip. In a solid icehouse a vented stove works much better, either wood or propane, NuWay makes a great little stove both vented propane or wood.
