Packrat damage- even worth fixing?

Hi there :) We have a 2005 Frontier Explorer (28') that we just purchased in the summer of last year. We own mountain property a few hours outside of Denver. Anyway- to the issue. It *was* a beautiful trailer. We went up to check on the property and trailers and found a jaw dropping (in my opinion!) scene- a packrat (or several?) had somehow made it's way in (I still don't know how- it's SO sealed up!) and literally damaged everything. Electrical, trim around most cabinets/counters, blinds, plumbing hoses, and pooped/peed on EVERY solid surface imaginable (did you know their pee is pretty much the consistency of tree sap? holy cow.). I'm attaching pictures for your viewing displeasure- what on earth do we do? Is it even worth cleaning up (we cleaned for a few hours, but dang- it's so bad) and repairing all the wood/electrical/plumbing? Where would we even start? I'm heartbroken- it was such a nice trailer!

Thank you!!
