Will pay $200.00/Month. Looking for space to put self-contained RV for 2 months

I am a 60 year old Ship's Captain and I will be attending a Professional Mariner Training school in Jacksonville, Fl. for 5 or 6 weeks. I have a 30 foot, self contained RV and I am looking for a yard, farm, ranch, driveway, or vacant land where I can park, sleep and study. I have no need to enter your home. I do need an electric connection and a fresh water hose. (I will move to a pump out station as needed, possibly once a month). It is just myself and I would be extremely quiet due to the massive amount of study and testing that I need to complete.
