I've had my 2 heaters on the back doors for the past 3 years, never had any problems with wind or rain. I always work with the doors open as I don't do dodgy neighbourhoods and what is there to pinch? bucket squeegee & applicator, big deal. I never run about without turning the Gas off. I secured the gas bottle with a ratchet strap around the middle of it, perhaps it should have its own enclosure. What I don't have are the hazard stickers for the van, I'll get on to that.
