She could not see any faults in Jones’s strategy. These men dared not park the RV in a campground or a Walmart for any length of time. RV encampments were, by definition, transient. But they had many of the social dynamics of a small town. Essentially all the residents would be white middle-class retirees. Jones’s crew of Pashtuns and Yemenis would draw attention. But an RV in movement on a highway enjoyed a level of isolation from the rest of the world that was nearly perfect. All its systems—electrical, plumbing, propulsion, heating—were self-contained and would continue working indefinitely as long as fuel and water were pumped into its tanks and sewage removed. They stopped occasionally to take on or discharge fluids, and though Zula couldn’t see much, she assumed that Jones was careful to select fueling stations out in the middle of nowhere and to pay at the pump, obviating the need to go inside and interact with any humans. He seemed well supplied with credit cards. Some of these had presumably been stolen from the dead RV owners, others perhaps contributed by the trio from Vancouver.
