Hi guys
Just discovered the forum and this great thread on the Landmann Kentucky smoker. I have one of these smokers and I have cooked some amazing pork shoulder and ribs over the past 2 years with it. Here's what I've learned:
It leaks like hell. I never bothered sealing with stove gasket but after reading this thread I intend to soon.
Fire and temperature management is very tricky. Weather conditions can easily affect your fire and the thin metal is not conducive to stable temperatures. In order to get a predictable and clean burning fire, I use a USB powered mini fan to provide plenty of oxygen to the fire chamber. To prevent ash blowing into the cooking chamber and onto the food, I installed this wire mesh between it and the fire chamber.
The in-built themometer is completely useless. I use this instead.
Here's a video of my baby in action:

All in all, this is a decent starter smoker. As with all smokers, you need to become familiar with its characteristics and learn how to cook effectively through trial and error. With the mods folks have suggested on here - and with how cheaply you can pick one of these up for - you can't go wrong really.
