folk do it , most of them dont give a shit to safety or REGs and quote *im not dead yet so its safe*
reality is many dont actually know what the **** they are doing and are risking pyrolysis of near by wood in the most part – coupled by it being a small space and things getting dropped/stored near it and melting/catching fire and many of the chimneys not being long enough for a full draw so risking poisoning them selves.
We have a truma(the one propex cloned) in our van – gives instant heat and has the van up to temp in 5- minutes or so(and its a big van) and more importantly if i need to move – i dont need to put out the fire , i turn to off and im ready to go immediately.
i dont see why you’d want a wood burner in a van (even though i have one in the house) even the “fuel” aspect of it. You still have to carry fuel – or youll have to buy it when you get to where ever – your unlikely to find ready to burn wood where ever you parked.
look at propex ,Quiet , cheap easy to fit , safe and thermostatically controlled (means its great for keeping a constant temp through the night)
