9k for the trailer itself, but...it's in Alaska. He may be trying to recoup transportation costs charged to him by Scamp
and whatever other way he used to get it there. Looks like Scamp only ships to the continental states.
I would expect anything in his location to have an upcharge for such things. Even if he drove to Backus to get it. I bet it wasn't cheap!
It has a wierd front window.. does it have a bath? They forgot to mention that in the ad. If so, it's an 11k rig.
