Hi all, I got a Masterforge upright propane smoker recently. http://www.smokingmeatforums.com/products/master-forge-double-door-smoker It's a good starter, and since I'm new to all this that's a good thing. In any case, it seems to leak a lot of smoke from the two doors. What can I do to keep more of the smoke in? Anything I can do to get a better seal on it?
