Cooking inside with propane
What's the difference between camping propane stoves (such as a Coleman two-burner), and built-in stovetops (such as SMB provides), that makes it safe to use the latter inside the van?
In a ventilated space, such as a van with top up and PH windows opened, is it ok to use a camping stove for things like boiling water? My natural reaction would be 'no way!' but I'm often guilty of being over-cautious.
