I would keep POE in the list of options, but I'm afraid it may end up breaking the budget. Currently wire is buried to each hook up location for the cable boxes and terminated in an outdoor box. each person has to run a cat wire out the window and plug in to the for the tv service when they are there. Internet could be done the same way. Also though, the only way the RVs move are if the river floods or one is upgraded. the power is left on from the time the RVs are opened in spring until they are closed up in the fall because of food in the refrigerators. Lightning is always a concern, but probably no more than phone and power cause too. Oh, and I think the RVs are all fiber glass and other composites instead of metal.
