I haven't altered the smoker in any way.
I do use the A-Maze-N smoke generators in the smoker.....they all work fine without any modification.
I bought the smoker mostly to smoke sausages and cured meats but I have smoked Q in it a few times.
The only accessories that I've bought are the James Jerky Dryer and 3 sausage rods.....the sausage rods are ok but I wish they were a bit heavier....3/8" or 1/2" instead of 5/16" I think it is.
If you have any more questions please don't hesitate.
