I've been getting barely any sleep stressed out that the ceiling will rot and fall down on my truck or tractor.
You are OK. Drywall is fine being wet as long as you can dry it out and you have some time to do that.
Good idea on the vents but like you said, without raising plastic there won't be enough gap to vent and not cutting plastic would be impossible.
I think it's possible. I wasn't sure about my cuts, so I backed off my pilot bit and went pilot-naked with my hole saw for the first bit. I then finished off the hole without the drill and turned my hole saw by hand because I wanted to keep the holes tight. As a result, I don't need any adhesive for the vents.
I cut a small 3" or so slit in plastic about a foot out from the W on each side of the truss. I then black taped a 4ft 3/4" and a 5ft 1/2" clear poly tubing side to side inside the end of my shop vac hose. I taped a fiberglass driveway marker to the 1/2" hose so I could shove it in the cavity all the way to the far end easily and the larger 3/4" hose along side it for extra sucking.
That's a slick plan. Since you have access from the top you can cut the plastic all you want to get pieces in there to tent it or whatever. We now have poly tape to use and you can tape up any slits you make, assuming you want to keep a vapor barrier up there when you are done.
