I don't see a downside to three bolts. I used three bolts and it does avoid the rocking that you could have if you used four bolts. Before someone jumps down my throat, I'm not saying your grate will rock if you use four bolts but the chances of it rocking are much better than if you used three.

Most every set of instructions seems to recommend 4 bolts or mounts to support the cooking grates. Why 4? Three would be easier and would not rock if they weren't perfect.
I've seen 3 used and suggested by a seemingly knowledgeable UDS maker on youtube and have seen pictures of at least one UDS in this thread with only 3 supports.
I've yet to see a discussion (I admit I'm only on page 75 here but reading more whenever I can) of the negatives of only 3 supports. Maybe the grate would be a bit less stable but I don't see how it would be.
Can someone tell me the negatives of only 3 supports?
