That is not a good idea. The exhaust could potentially be blocked by snow. If that happens the furnace will shut down.

Not only no,he'' no. The primary reason the furnace doesn't retain heat within the trailer by exhusting indoors is carbon monoxide. It's been years since I awarded anyone the Green Winniy Award but here you go 1261. I'm sorry mike but for only offering possible snow blockage as reason not to do it,,,,,,,,,,well you understand don't you?

You are right, the potential for carbon monoxide poisoning is even more of a reason not to do it.

To ask a question like this, wow... they will probably do it anyways, even though they risk DEATH...

Now that you bring it up Vith,I have a question of my own. How many deaths were labeled suicide over the years when in fact the guy was attempting to get the car warm before leaving for work. Do y'll think lawyers of widows might use that theory in convincing life insurance companies the death was accidental? Not only would that make the claim payiable,,,,,,,,,,,double indemnity clause applies.

sounds like some snidely whiplash stuff right there. :P

Huh ohhh,I had that coming. Touche
