After seeing another post with the same question (maybe by you??), I visited their web site just out of curiosity. Seems to me that if you parked in one of their non-airstream lots for a month or so, you could ask around and surely find someone who was near selling. You would also get a feel for the place without the commitment. Of course, if you've already done that, well, ....hopefully someone on these boards will give you the response you desire. Best of luck.
