When I started looking for Airstreams back in 2008, I had a very similar budget. The answer to what you can buy for $12k?
- A 60s or 70s trailer that's had a lot of work done to it to keep it going/update it. Like houses, a vintage trailer is never "done" (I own a vintage Argosy)
- Newer trailers start around here
(1998 Bambis for around $14k.) It usually takes some looking to find one - going into winter is a good time to look. Otherwise, it's the curse of the "Bambi" name - lots of people want them, driving up price and demand (and Craigslist fraudulent ads listing them for $6000 for a 2000s trailer.)
