Even though I haven't been "home" (Satellite Beach) in several years, I continue to browse Craigslist in Treasure Coast and Space Coast regularly. There have been several sweet Airstream ads that I have forwarded to my cousin (in Pt St Lucie) but I can't convince her to purchase.
So, I'd just keep on looking!!! And when you find one that you are interested in again, look for an inspector on this site. Invaluable!!!
I bought mine in Melbourne, knowing 1/4 of what you already know.... I have done a lot of work on her (axles, floor repair, electrical, etc) - thankfully she's always been road worthy and usable. I've collected a ton of "projects" that are waiting to be complete (fabrics, paints, new range & refer, etc) but the work is hard when you can't store it at your home... And traveling to/fro a storage lot with a generator is tiring.
Also, I towed my 27' all over south FL with a Xterra. I never once had any difficulty. But a few folks suggested I was unsafe, especially if needing to stop on I-95, and I upgraded to a full size SUV. I still don't think it was absolutely necessary for my driving at the time, but now that I've towed cross-country, I know the larger truck was a good investment (for mountains).
Good luck to you - wish I was "home".
