I am also looking to install a small wood burner in my campervan.
Of course the stove does need to be small as its surprising how much heat they give out in a small space.
Now my van is not that large and a permanent floor mounted wood burner would take up a great deal of space, so my thoughts are on getting one of those take apart stoves designed for tents. I can make a hole in the roof for the flue and then blank it off when not in use.
Is this idea crazy? Am I missing something? Surely this is much better than having a fixed permanent stove that probably would only be used during the colder months.
