Sealing Holes...

steel wool type material is a good deterrent.

Spray foam.

DO NOT seal the bottom of the propane tank bays!!!! You can seal the openings for the cross over pipe, and over head openings.

Use bronze wool, won't rust.

Propane is heavier than air, screen but do not seal or it could go boom.

Why in the world would you buy a new trailer and then afterwards be concerned about all unsealed access holes? If the people at Montana could not be bothered to seal up all the access holes that mice, rats, squirrels, and what ever else can get into your RV and destroy it, I would hate to see what the builders buried in the walls and where you can't see.

I agree with this. We looked at several new Montanas a couple of years ago and were very close to pulling the trigger until I noticed all of the huge openings all over the trailer. We had rats get into a fifth wheel that we had several years ago which was not pretty, and I could easily see that happening with what I saw with those trailers. I just couldn't see paying what the dealer was asking for the trailers and then have to deal with that.

To the OP, I would stuff brass wool as tightly as I could into the holes and then seal them up with spray foam. Be sure to take your time and look over the trailer carefully because you certainly don't want to miss anything. Good luck.

I used spray foam on all the openings.

bingo, same here. I live out in the country and we have ton's of field mice so I'm constantly keeping an eye on that and making sure there are as few entry points as possible.

But the people at Montana don't live in or own the RV, so their perspective is different than the new owner.:S If you buy a brand new house and the builder didn't install window shades are you going to leave it that way??:E
