Are you running a dehumidifier in there when you're not camping?
I thought about that, but having them sealed seems like a better alternative to giant holes in the floor. To each their own I suppose.
I wouldn’t leave them open into the crawl space of my home and it doesn’t seem like a good alternative in a camper either. Great stuff is easy to remove when it’s cured. Most places, I can pull the edges of the screen and it will come out in one chunk.
Getting to any connections to tighten may be a bigger challenge than the foam. Under the shower drain I actually left a small place to allow drainage in the event of a leak. It actually leaked when new. The fitting cracked which I replaced with a rubber Fernco connector. I believe it’ll be much better long term than a rigid joint.
Also, being foamed in should eliminate a good bit of movement and vibration in those connections possibly preventing leaks too. I hope my theory plays out.
As for a dehumidifier, I leave the AC set to 80 all the time when parked. Probably wouldn’t hurt to have a dehumidifier too though.
