I found this when looking for a boat heater. I can definitely see one of these mounted in a wood-panneled van, vented through the roof. I don't think it could be made to work with a pop-top though unfortunately.
Tempted as I am to wander into the nether regions, I'll play this straight: stoves like this have a little jet in the burner through which the pressurized fuel travels to be ignited. Self-pricking stoves have a little automatic cleaning wire that ensures the orifice does not clog with soot, grit etc. It's usually activated and withdrawn as you open the valve.
Similar to the Svea stoves. My old 123 stove doesn't have the self cleaning tip but the newer ones did. The heater seems more like it's built for a boat cabin. I also can't get past the exhaust but it sure is cool looking. I like it. As well as the stoves work, I'll bet those things work great.
