Getting $1925 worth of parts out of that trailer is going to be tough. The upper segments aren't worth much, being made of flat metal. There are no appliances of any value as far as I could see. Window operators, door lock, some of the unbroken glass ... a few bucks for that stuff.
Keep in mind that a "sale" on eBay is often not a sale. When people figure out the real cost and condition of what they've just bought, they often back out. It would be so interesting to follow up on a dozen eBay wrecks like this and find out what ended up happening ...
