Thanks for linking that video, that was useful and definitely good information. Simplifying everything to run off of gasoline (engine, stove and heater) would be very convenient.For international travel in a gasoline vehicle, I would only choose a coleman stove (pick your needed # of burners), and just use vehicle fuel. A cleaning kit for the generator tube and perhaps the proactive use of fuel injector cleaner would also be advisable.
If I had a diesel vehicle, then I'd be on the fence between still choosing a coleman stove (since gasoline is ubiquitous), or a diesel stove for common fuel usage.
