Put a few holes in the lids, thats is what I do. I live in sout Florida. I burn 14 holes long the outline of each 28qt lid.
Lets see theres about 15 holes in each lid, 10 holes on each side of the tub, and condensation is pretty bad still. The close they are in is around 80 degrees, so with the tubs being around 92, i wouldn't think thats that big of a difference.
