I have run a few smokes through my Char broil, and I'm less than impressed with it. Making trips out to check the fire every 15 minutes ain't doing it for me. As well as the unit seems incapable of keeping up with -25C temps. And since the majority of my year is spent below freezing, my rig should be able to put up with it as well. I'm looking at the Great Outdoors Smoky Mountain Series, and I'm wondering if these units will keep their heat up in the Canadian North. Thoughts? Pointers?
