This picture touted the internet as Redneck Mansion. As variant of this: nice idea for a caravan treehouse as well, almost like in the Belgian movie Koko Flanel staring Urbanus. In this movie he pluges a caravan into a tree.
The collection of trailers and a caravans is actually an outdoor theatre set. Build in 2005 for Theater Het Amsterdamse Bos to host the Anton Chekov play Ivanov: A story about a guy who has lost something.
