I met a new vehicle dweller today. He lives in a Jeep. No matter how closely you scrutinize his setup, you simply cannot tell anybody sleeps in there. He built a box behind the passenger seat. If you open a plywood cabinet door, there is a bed inside. Until he actually holds this open to show you the bed, you would only see a Jeep with some tool storage in the back.
This guy is clean cut and young. He wears fresh crisp clothing and a grin. He is invisible.
