What to do?

Make them into smaller modules. You should be able to do minimal damage to the scenery. Then, some fresh lumber to finish the framing of the cut ends. Careful marking of any wiring and some connectors can make reconnecting the harness a simple task.

I feel that doing this would make it easier for you to use it or sell it. The other option is to repurpose everything salvageable and build a new one.

Pictures always help for something like this. My best guess would be that the 8x8's have to be separated into 4x8's, moved inside and then reassembled and patched at the separation. Will require some surgery on your part but should be well worth the effort if you like the layout and have the room for it.

It all depends on how much someone likes the layout and its level of craftsmanship.

Building new is almost always easier in the long run than adapting a layout built without moving in mind when it was planned. This will hurt any attempt to find a home for what's on your trailer.

If it doesn't have the features that someone really wants on a layout, they won't be happy in the long run and would be better to start fresh. Anyway, the old layout could be a good source of lumber that you could recycle.

Thanks for the suggestions. This layout, though older, is too good to scrap. I'm not sure about breaking it into smaller modules, I don't think it's laid out appropriately.

I have pictures on my phone, I'll try to get them here somehow.

Windows? I remember my grandparents trying to remove some of the furniture that came with (ie. designed with) the home. The couch, and dining room table would not fit out of the doors! Turns out they were put in before the build was finished, and had to be removed by taking out the separately framed and glazed picture windows(3 layer). Yes Grandpa wanted to chop them up, but Grandma threatened more new carpet if sawdust got everywhere. He hired glazers, who helped move them out too. 

   Try looking on Craigslist or similar for a local homeowner with a garage, or part of one, to rent out. People rent them out for old car storage cheap all the time, I cant really think of why a layout would be refused. A wanted ad wouldn't hurt if you don't find one immediately. Set it up there, and use it to get away from the house on occasion. More money, but many public storage areas have heat, air cond. and electricity in them too. While moving around, a pal had a couple units years back. Built a hotrod in one. In the other one we hung out, drank cold beverages from the fridge, coffee from the pot, sat on his old furniture, and watched TV till our knuckles stopped bleeding. When a building isn't practical, small businesses around here often use them as "bases" as well as storage. 

Maybe some special group (retirement home?) would have room for storage in exchange for some holiday/special event "train time" by you. 

  Splitting it into smaller sections? It may require some additional reworking of scenery, but if its as sturdy as it sounds, and cant be saved otherwise, why not?  Pictures of the underside and top. Please...before I get to a thousand words.
