Anyone have the Blaze King King 1107? I was looking at the manufaturer's listed specs, and it reports 40 hour burn time? Is this greatly exaggerated, or what? That doesn't even seem possible. I understand that the firebox is 4.32 cu. ft, but my Isle Royale with 3.0 ft firebox has trouble making 6 hours. Granted, I could use some new gaskets. Regardless, 40 hour burn time seems way too high without a WHOLE lot of smoldering. If anyone has any accounts of their burn times with this stove, I would be grateful.
