Unless the thing has been ultra renovated and customized (WITH DOCUMENTATION) then run run run away.

For that price on that model I would have to look thoroughly in the basement.
And that is not easy to look at. Id have to see paperwork on the axles. Are they Henschen (brand)?

Just too much for a long distance purchase.
Remember when it comes to selling things that roll most sellers seem to have some ethics hiccups. Er lets at least say an undeniable urge to exaggerate/embellish etc.
You get the drift. If it was nearby and you had time to do your due diligence then the price is entirely up to the two of you.
But pray tell how you can do DUE DILIGENCE from far away or on a quick look-see.

Speaking of praying;...Airstreaming is (for most) an avocation. As I have said elsewhere it is not a Religion.
The so called "airstream spirit" is certainly not Holy.
Trust at your own peril, Verify Verify. If the seller is insulted or does not agree, throw them a kiss on your way out.Their "airstream spirit" should know better.
