If you're willing to do the removals yourself, I think you could do very well parting it out. There are a lot of things that make up a trailer...check out the "new" cost of things like heater, converter, fridge etc. It's only six years old, for cryin' out loud!
Even a single RV window could be worth a hundred bucks to SOMEBODY...and once everything of value has been stripped, you could haul the plucked carcass to the dump/ wrecking yard and leave all the trashy body behind, just going home with the bare frame behind you. A street-legal, Titled trailer frame (with brakes) ought to be worth a nice chunk of change.
Thing is, it will take awhile. But if you're patient, I think you could at least get what you owe. Under NO circumstances, though, would I recommend that you allow anyone to do the removals themselves...that could leave you with one heck of a mess.
