Bagging insulation?
Ok before I seal up the belly pan do you think this is a good or bad idea? Plastic wrapped insulation to prevent getting wet from whatever source. Thanks, hoping I can upload pictures.

If you're not going camping in the middle of winter, the best idea is to leave out all the stuff the mice like to play in. I never replace insulation in the belly and have not noticed any reason to have it there.

We will be living in it while we build our home in the mountains. 9000 ft that is why we need floor installation.

Hi
The very basic issue with doing anything like this:
If you make it tough for water to get in, you also make it tough for water to get out. It takes longer to get wet and may never dry out ....

Thanks Bob, that's what I was thinking too on second thought, and was looking for some confirmation probably not a good idea. So better to seal everything as good as possible. Thanks for replying.

You don't want to do that. It will eventually get soaked and stay that way. I would use 2" rigid foam with a slight separation between it and the floor so water can get out if it gets in. Leave a path for water to get out. You will loose the most heat through the shell since the ribs conduct heat well. The radiation barrier shiny bubble wrap would be good to put over the windows when it is really cold. The good is that it will heat up quick in the sun.

Use rock wool insulation instead of fiberglass, it's easy to use down there, water repellent, mold resistant, and rodents don't like it.

I'm planning to use rock wool. What are people's thoughts on a few strategically placed, screened, small drainage holes in the belly pans?

I would think rockwool would absorb water also consider the weight aspect of it. How much does it weigh compared to foam? Can you tape seams to reduce air flow?

If you tow your trailer in the rain it will get wet in there. Fiberglass insulation sags from age and vibration. Some will undoubtedly be in contact with the belly pan. Then it wicks up to the plywood floor.
My next major job is going to be removing all of it.

Keep it from laying on the belly pan directly and some small drain holes will be fine. Kee them small, 1/8" ish.
Rock wool is hydrophobic and doesn't hold water, weighs slightly more than fiberglass.
A couple inches of rigid foam would definitely be my choice. Doesn't stop critters though.
