Building an RV park. Advice needed.

[Chantz Ireland]

 cannot seem to find much discussion on Rv parks and how to obtained them. Mobile home parks look like a good idea but I really want to focus in starting a RV park. Basically tentents live in their RVs on my land and pay me a fee each month.  

I was wondering if anyone new what it took to actually start one, what permits I would need and the type of land?  

I need a starting point, anything will help. Thank you!
