wouldn't be surprised if its bought and sent to china for copying
Why would anyone bother?
I had a really good look through one at Farm Fantastic in Caboolture a few years ago. No, it was not a mirage or dream.
It made a lasting impression on me and my wife. It was
massive and had acres of canvas. From memory it had an electric setup to erect part or all of the frame. At the time my thoughts were it would be a nightmare to setup even in ideal conditions. In wet and windy conditions it would have been a disaster. If one needed a large heavy setup like this, a caravan in my opinion would be a much better alternative. It would have been no easier to tow than a mid-sized caravan and access to many more interesting camping areas and National Parks would have been all but impossible.
