I got one,... complete waste of time and money IMO.
It only kicks out 300 watts of heat, and it STINKS the whole van out with a horrible paraffin smell. It also has a tendency to smoke a lot and it fairly destroyed everything in my shed with black soot one night!
I used it for a week,.. and then started filling 2 barrels with hot water in the bath, putting them in the van and throwing a blanket over them so they didn't leave the heat out too fast.
I still think is you can get power to the van, an oil filled radiator with the thermostat turned down low is prob the best solution,.... or a hot system to pre-heat your main wfp tank,.....
