I looked around, and it looks like it's around $6500-$7500 through a dealer, and if you order directly from them $8500 (incl. tax).  It was hard to pin it down exactly, but they appear to have a base model and one additional package you can buy which could explain some of the the discrepancy in price. 

While it's cool, it still *feels* too expensive for what you're getting (a small cargo trailer and a tent on wheels), even if it's state of the art.
