Yup. That's what I finally resorted to. After I discovered the uneven bottom and the reverse tilt. Which, of course, didn't appear until after I discovered all the 857 other things I discovered that the evil shop genie put there to mess with my brain.
So far today the humidity is at 17 percent and it's an even 100 outside right now so the swamp cooler is working fine. The air coming out of the plenum is 78 and the shop is holding at about 86. So the acid test for the a/c unit is still in the future.
