    I cut out the soft spots to open everything up so I can dry it out. Everywhere that the ceiling was not soft and the luan was still bonded to the styrofoam, I cannot get it apart to be able to replace one giant sheet on each end. I really don't want to tear down the styrofoam as it seems to be in good condition and also don't want to destroy it trying to take down the areas that are still bonded.

    I went to Lowe's and home Depot yesterday and couldn't find any plywood that was thin enough to match the existing thickness.
    The only thing that I found at Lowe's that match the thickness is this: http://www.lowes.com/pd_15483-SS1254825-46498_4294937087?productId=3014304

    I also thought about patching it in with that link above and then going over two sections with a solid piece of http://www.lowes.com/pd_518477-518477-53547_4294937087?productId=50121135 so I don't risk seeing any seams through the wallpaper but I'm wondering if it'll be too much weight pulling on the ceiling. Everything seems fairly light but I don't know what the ceiling can hold.

    Do yourself a favor and cut more of the ceiling away. At minimum, cut back to the roof brace in the picture. Otherwise,when trying to piece in new sections of ceiling, it's going to look like crap. I had a very similar situation as you. I cut back to the roof brace, and replaced used 2 sections of luan with a seem in the center. I glued and screwed to the wood roof structure. And used a piece of trim to cover the center seem. Then I painted everything white. Sorry the picture is not the best. 20180427_171518.jpg

    In the front section I tried to remove all of the wood, but where it is still glued to the styrofoam it doesn't want to come away from it. I'm afraid to tear chunks out of that styrofoam trying to pull the Luan off of it.

    In the front section of the camper I don't want to get too close to that rail that holds the door when you put the door up to put the camper down

    The foam is not structural. If some breaks off you can replace it...it it's basically 1in pink foam board from home depot glued on both sides. Considering the water damage and what looks like mold in your pictures, I would remove it anyway. Think of it this way, you only want to do this work once right? Here is a picture of what mine looked like after I removed the damaged section.

    I was going to put a thin coat a kilz over that styrofoam. and if I look at yours, you have a lot more wood supports running through your roof than I do

    With less internal wood support, you'll have to get creative and definitely use more construction adhesive. You may even need to create some support structure below the patch until the glue sets up, to keep the panel from sagging.

    When I put up the panels I'm going to make braces to hold them up while the glue dries.

    I was out there poking around a little bit ago and I just can't figure out how I'm going to get that ceiling separated where it's still glued. I do not want to remove that styrofoam, I'm just going to paint it good with a thick coat of kilz

    You could use some sort of blade between the wood and the insulation to separate the two. If you end up removing more insulation than anticipated, it's easily replaceable with new sections.

    Also, I could be wrong but I'm not sure applying a water proofing paint to the insulation is advised as it will seal the water in. Much like the flooring, it needs air to breathe so no paint.

    My wife is having bad anxiety about removing the existing styrofoam. If the styrofoam seems stiff and not saggy I wonder how compromised it may not be that I can just let it there rather than replace the styrofoam also

    Of you paint the styrofoam use latex paint, no oil or rattle cans. It could melt it. Some glues will melt it also.
