UDS Build - Two Cooking Trays
I'm looking at putting together my first UDS in the next week or two. I've been researching this for a few weeks and I would prefer to have two cooking trays in mine. I know I'll likely have to put in a diffuser tray to control the heat for the lower rack.
I've seen several designs that explain the cooking tray should be 20 - 23" from the coal basket; but, I have yet to find any designs with positioning for two trays. Does anyone have any suggested specifications or links that would point me in the right direction?
Any input would be greatly appreciated. Thanks!
