Hmmmm....Why do I feel the need to have a door? Also, are there two tiers of cooking space or just one? If there is a second tier and you have to go in from the top, isin't it a PITA to have to take one grate out (with meat on it) to get to the other grate?
if you put a door in it, you take away the cooking effects of an UDS...people have done it but the idea is to keep it fairly air tight with constant draw..you cant get a good seal on a door thus taking away the convection idea..
on this cooker there is only 1 grate as i am using a flat lid... for the option of having 2 grates a kettle lid is needed. as for PITA for the 2nd grate, its all about smoker management... meat that takes the longest goes on the bottom..butts,brisket etc etc...ribs and whatever else goes on the top grate..
