It's hard to answer this! 180 for 7 month permit LTVA, 14 day stay areas the rest of the year!!! But that is deceptive. If you use a generator fuel regularly far exceeds utilities in a park! Amount used in fuel to move depends on how you move! If you choose solar there is maintenance that should be figured in.
Costs in frustration while you learn the ropes, don't have a dollar value, but you should place a value on this valuable commodity!
All in all, done right likely 150USD per month!!!
