You might be thinking of Chalet #1385, which was the one that came out of an estate sale, then changed hands a bunch of times since the summer of 2010. I found
this web site just recently which seems to track 'sold' eBay listings, and you can find it if you do a screen search of the word Chalet. As near as I can tell on my own, it was a legit sale for $21,500, 'cause I checked the seller's eBay feedback page for two months until the buyer finally put in his feedback.
The #0258 one is the story where our Yahoo Chalet forum member had it for years, sold it on Craigslist for $3400, and that RV consignment lot turned around 9 days later with it for sale at more than double the price. What got me was that whoever the seller is re-used the identical text out of the previous owner's Craigslist ad in his first eBay listing, which then misrepresented how long the seller owned it. The prior owner and I both protested to the seller to knock that off, and at least his 2nd eBay listing erased references to the length of it was supposedly owned.
