[VAC] venting & gas heat

[Jill Hari <jillywonkenobe@xxxxxxxxx>]

I was perusing "The RVers Bible" at the bookstore
and saw something about gas heaters in RV's, that
you should NEVER have a gas heater in an RV
because of the fumes, but then I got confused
because a few pages away they were talking about
propane heaters in RV's (I'm no rocket scientist,
but propane is GAS, right?). I though gas heat is
pretty common in RV's - am I'm WAY off? 

It got me kinda worried - I have always preferred
gas for everything... heat, cooking, clothes
dryer, water heater, etc.
