New Fiberglass Airstream "Nest" -- Yikes! "only" 45K!

I wonder why they only have a 12v/110v refrigerator. Seems to me a small trailer like that would be great for some serious boondocking but with the refrigerator dependent only on electricity and two small group 24 batteries the time allowed would be quite limited. They have propane on board for other things, why not include the refrigerator on gas too?
All they need to do is increase the price by another $4000 or so!:E:R
