How much smoke does the Yoder YS640 produce?

I think I am this close to getting the Yoder YS640-but I am wondering how much smoke does it produce? I want to smoke Beef Jerky at 150, but since I cook it so low I want to use smoke to cook the meat, not high heat. So how much smoke does this model produce? And what is the concept behind their firepot design anyway?

I have one and use an amazin tube smoker if I need extra smoke, but in my experience, for jerky, I haven't needed any extra. Adding the tube will allow you to cold smoke when ambient temp is low enough.

As to how much smoke does it produce, (which is impossible to state accurately) definitely enough, especially at temps below 200.

Thank you! really appreciate the response.
