Question Upgrade of trailer house exterior wall

Would like to remove exterior exterior tin, install better insulation within wall cavity and than install siding on exterior vice the tin. Was looking at using 4 x 8 sheets of siding (T-111)? Is there anything special that needs to be done other than removing the old and installing the new? Should the insulation be installed with the paper side out or in? I was hoping to install it with the paper out, to allow me to staple it to the studs and help better seal the wall. Do I need some sort of vapor barrier?
Has anyone else tried this?

Thanks in advance.

I just joined today looking for this very information, please if anyone can answer this for us please do. I have tarp over half of my house as I type. Thanks to Hurricane Jeanne a few years ago and no help from FEMA.

A lot depends on the MH.The MH's with aluminum sheet siding have all the studs notched with 1x2's running horizontally - this is what the metal is screwed to. There may or may not be enough insulation in the cavity - packing it in there makes it less efective. Most MH's have 2x4 exterior walls although some of the cheaper ones have 2x2 ext walls

The biggest problem is sealing the new siding at the top. Unless a roof over has been installed it will be difficult to flash and seal the top so no water gets behind the new siding.

Guess I will see how it turns out. This trailer has a 4 to 6 inch roof over on it, so was hoping to be able to get siding under it, to prevent moisture from getting behind siding. Lady says she can feel the air come through the wall during windy days and is hoping this will prevent it, or at least slow it down some. Was thinking, may have to put up some tar paper prior to the siding, just to help seal and insulate it some more.

Thanks for your input.
