One bus I had for a short while has some sort of gasoline heater, but no way in hell was I going to try and use such a thing.
I had a ‘63 Volkswagen bug the heater of which consisted of opening up a valve to who-knew-where and enjoying about as much heat as lighting a match gives.
Lol. Yes, I heard about the gasoline heater. Apparently it was installed under the drivers seat. Absolutely not. I’d freeze first.
