Adam, thanks for the pics of the 41 qt tubs, the tubs I was planning on using are the sterilite 1960 and the only difference (besides the height) is an eighth inch greater width. How much extra clearance do you have when you slide the 41's in from the side? If i'm calculating correctly on the 24 inch shelf minus 5 inches for the posts there should be ample clearance but it's kinda hard to tell in the pics. . .
