I had three smokers (nothing like this) and lost all 3 in a tornado. I just replaced all 3 with this smoker. I had a USD I made, a Masterbuilt (which I will also replace) and a grill/smoker combo.
This is a reverse flow smoker. The fire box has access from the top or side. The grates slide out for easy access to add or remove meat. It also has a propane line and wand to start your fire. The front smoke stack can be closed.
The tank in this photo holds water and the line runs it to a place to put a pan (I think that's right) to keep moisture in the smoker.
