Thanks! This seems like stuff that I can do. I was thinking of making it so that the tubs can stack atop one another, with veltilation on the sides. Or maybe stacking them and putting 2x4 pieces in between to make it do-able to ventilate the top after all. Basically I want to stack tubs without building a rack. Thinking, drawing-up plans and the like are in my future. Might just build a rack.. we have alot of scrap barn wood that I could finangle into something..
