Depending on the state the hookups can be quite easy to manage. If I recall correctly Kentucky doesn't have strict rules in regards to septic systems and the land there is quite cheap.
Actually a lot of places in the US have cheap land. It might even make sense to just cash buy a bunch of parcels all over the place and move between them.
It would most likely end up cheaper than renting land every six months and you have control over it (plus it's a potential investment due to resale)
Electricity via solar panels since you wouldn't need much anyways
