But his wasn't an RV (responding to 2 comments because you both said the same thing). RVs like the type that rock stars use are really nice, and very expensive. His was a 5th wheel - you can't drive it. It attaches to the back of the pickup truck. It is smaller and not as nice. (From what I can tell from the helicopter shots). I just wonder if anyone has any record of him owning a home somewhere. He did at one point have a wife and 2 kids.
Also, that camper he lived in is mobile, so how long had it been there? Is it possible to check Google Maps from 2015, 2014, 2013, etc. to see roughly when it showed up there?
