Unfortunately, yes you do need it. That cloud is designed as "hard backed", because it needs to deal with some modal and SBIR issues in the vertical plane. The only way to do that is to put some decent mass on the top, and hang it at an angle.One other question...Do i need to go with MDF on the backing for the cloud? It adds considerable weight which makes installing it harder and a bit more dangerous.
The good news is that the new design has some holes cut out of the MDF, and it isn't 100% coverage any more.
It's not that much harder to install with the hard back on: you still have your "come-along" winches that you used to raise the inside-out walls, right? Or maybe rent a heavy-duty drywall-lifter for a day to help get them up. Or "rent" some friends using pizza and beer, and get them to help you.
Lots of ways to skin a at.Dangerous? Yes. It's just as dangerous as raising any heavy object up over your head, but if you do it properly, taking precautions, and anchoring it correctly, then the danger is minimized. You've already done far more dangerous things, such as raising the inside-out wall sections, and even more so the inside-out ceiling modules, so you know how to do this. The only different thing here is using chains and bolts to anchor it all in place. Use the normal safety precautions and "rules of thumb" from stag rigging. In other words: everything rated for ten times the weight it will actually support, full-loop hardware (no hooks!), welded not just bent, etc. I'll give you some more pointers when the time comes, but following the safety precautions will make it no more dangerous than anything else you have done so far. And once it it is in place, it is no longer dangerous, as long as you anchored it all correctly.

I do have a sheet rock lift still. Not as heavy duty, but it should work.
