Westy campers,

Does anyone have a preferred venting method while using a propane heater?
Side widows? Vent windows? Skylight? Combo? How do I know I'm drowsy from a
couple of Rolling Rocks, and not from coal miners syndrome? I'm all for
venting carbon monoxide, but would like to retain a little heat, too.

I use a Coleman portable catalytic heater.

Thanks!
