SO...if you're sure this constitutes 'safe' use inside a Vanagon camper,
please post the entire safety blurb across these very internet groups. I
doubt too many buyers of $39 heaters will bother to read the Mr Heater website.

But really--18-19%? Doesn't that sound just a little bit borderline for
safety? Does it also have any other safety features beyond tip-over protection?
