Yeah so it ended up being fake as heck - I could "see" it "when it got to my house after shipping"
It smelled fishy so I Google search and found a forum that had this same scam, using different names but the exact same story and the exact same wording.
On the bright side I found a real, better, not scammy find - a 1975 Shasta 16' SCS. For $900. Went to see it, she plugged it in and let me check it out - ac and plumbing worked as far as I could tell, no water damage. I didn't check the appliances as I plan to replace them anyway, but had things like string lights and electric clocks working, lights worked. Fridge worked too and had some snacks in it!
I loved it so much that I gave her 1200 instead of 900... and now I get a nice Shasta to make my own :) I've never been happier.
