Judging from your floor plan, my trailer is about the same size. My interior is finished so I will be removing the belly pans from under the trailer and instalingl the foam that way....

Judging from your floor plan, my trailer is about the same size. My interior is finished so I will be removing the belly pans from under the trailer and instalingl the foam that way.... On Mine camper the belly pan sits on top of the frame. That would require unbolting the camper from the frame and lifting the camper high enough to get the pan pried off, the foam installed then a new pan installed. If Yours is the same as Mine. An alternative method would be to drill about five holes into each section, then using spray in foam insulation with a tube on the cans and spray them full. Only problem would be determining where each section is. After I cut the belly pan for Mine camper, I had the pieces in place with the exposed side facing down and setting on top of the joists frame works, I then got underneath and marked each section. That way I can put a couple of screws into the cross supports to keep them from twisting. I then lifted the framing and tied it up with ropes through the windows openings, slid the top decking under the framing with the top side facing upwards, lowered the framing onto the decking and then marked each section so a couple of screws can be drilled into the cross frames from the top side. Without trying to guess where each cross section is located and drilling the pan and deck full of holes trying to hit them. LOL
The original builder had installed a very large sheet metal pan head screw into the joists and screwed them so they would go into the ends of the cross frames, they then put in two smaller screws towards the corners of the cross frames to keep them from trying to twist.
I think I like My method better. LOL

Just read your thread Marty....HOLY CRAP you did ALOT of work on the old girl! My friends give me grief over how much I have done to mine....
Like you, I bought an old trailer for ice fishing. You know how they are.....hacked up, abused and often of "unknown origin". I started fixing it up and then I got hooked up with these "vintage trailer folks". I have learned SO dang much just lurking around here and watching Mobiltec's videos. I DO plan on doing a total re-skin in the future.....
Back to the belly pan.... Mine rides on top of the frame rails, on top of the metal pan are the 2x2 joists then the floor. My floor is solid. I was thinking about cutting away the metal pan with an air nibbler & either spray foaming the entire floor from underneath or adding pink foam board then recovering the pan with ABS or treated 1/4in ply....
Any thoughts?

If the floor in Yours is constructed like the floor in Mine, that would be a lot of nibbling. Then, You had better take a good looksee, there may be plywood between the metal pan and the floors joists and cross members. If so, that`d be a mighty lot of work, trying to figure out where each section would be. It may be possible that once the pan is nibbled away, if in fact there is plywood above it, You might be able to tell where the cross sections are by the nails or screws. I am betting though that Your camper has the fiberglass insulation already in the floor. A smallish drill hole through the belly pan would do a quick test on that theory. It would be a mighty big undertaking without completely removing the floor and taking it apart. One option would be to put down a bunch of throw rugs, that would help a LOT. Extra thick ones would be better. This camper had the square tile carpets on the floor before I pulled it apart. That might also be an option, put down the carpet tiles then throw rugs on top of that. Anything would be better than nothing.

I did get a peek at whats under the pan when I cut in the holes to install the Catch Covers. Just sheet metal, and an air gap then the plywood floor. The pan looks like it was installed onto the frame and then the coach was built onto it. I THINK....based on what I saw when installing the hole covers....that I would be able to zip out the pans and address the insulation issue. I am leaning towards spray foam. Folks say it stiffens up the structure while providing excellent insulation qualities.
As for now, I have the entire interior floor covered in those 1/2in thick interlocking foam tiles. Like you said, anything is better then nothing. Last year, I had it out on the lake at -15f with NOTHING on the floor but the carpet....a little chilly!
I will know more in the spring. I will address this pan project then. Right now, I am getting her buttoned up and prepped for ice season....
