Building an RV park for overnighters?

I would think that a mobile home park may be more lucrative than an RV park. You have year-round use, more predictable income, and less manpower to keep it running. There's no dump station needed, no showerhouse, perhaps even no office needed. There might be some affordable housing state aid programs available to help develop it in some cases.

At least here in Vermont, the design and permitting for a sewage system for a campground would start to approach an extensive investment in itself, to mention nothing of its installation. It would likely be simpler if municipal sewer is available and had sufficient capacity.

Yep, I bet the neighbors will welcome a mobile home park next door. Also, once you have a mobile home park, most jurisdictions (and the renters) make it nearly impossible close up shop and move on to those higher uses the OP is hoping to capture in the future. The laws of many states are written to prevent easy mobile home park closures, for a good reason. Closing a mobile home park impacts the residents greatly. Not only do they have to move their belongings, like they would if you no longer decided to rent out your house or apartment building, they have to move their mobile home, which is pretty much mobile in name only.
As for "tiny homes", I am still waiting for someone to post links to actual tiny home communities. A few RV parks and mobile home parks have changed their names to try and capture that supposed market, but I haven't seen one yet that is actually a community of those homes. Until proven otherwise, I will continue to believe "tiny homes" as a movement exists only on Television. Yes, there probably is a movement away from McMansions to more reasonable sized homes, but that is a switch from 3000 - 5000 sq ft to 1000-2000 sq ft. Smaller, yes. But hardly meeting the definition of a tiny home.
