Defending my "DUMB design" statement...
Let's say you want to mop, flip, turn or otherwise manipulate the food on the second rack.
With a bullet such as a WSM:
1. Have a large clean heat-proof grease-proof place to put the lid so it won't leave a greasy ring on your deck.
2. Remove it and put it there.
3. Have a large clean heat-proof grease-proof place to put the top rack and whatever food is on it.
4. Carefully remove it and put it there.
5. Do what's necessary to the food on the lower rack.
6. Carefully replace the top rack and whatever food is on it.
7. Replace the lid.
8. Clean up the grease-proof surface you put the top rack/food on earlier.
9. Might as well clean up the lid ring while you're at it.
With a vault:
1. Open the door.
2. Reach in and do what ya gotta.
3. Close the door.
Blasphemy? You decide.
