Explain to me a bit how RV hookups work and how you could hook up in someone's back yard.
So I've been reading about RVs and camping trailers and also I love the idea of Tumbleweed Tiny Houses.
While it's likely just a pipe dream, let's say I get a Tiny House or an RV and wanted to hook up rather permanently in a relative or friend's back yard and pay them rent/utilities. (For the sake of this question, let's assume this is permitted in their locale or I get the proper permits.) I have Googled "how RV hookups work" but I'm not really getting it. I read how to dump a greywayer/blackwater tank but nothing about electricity and water. Is it like a single post you hook into with hoses and cords?
I know the three hookups you generally need are water, electricity, and sewer. (I'll assume heat is just a matter of hooking up a propane tank.) Water = hose, simple enough, I suppose, but wouldn't their pump be running all the time? I know our pump ran a lot when we used to have a swimming pool and would run the hose into it for top-offs. (Note: I have only ever lived in homes with well water so I don't really know about hooking up to city water supplies.)
Electricity... someone mentioned a really long utility extension cord, but would having one of those overload their circuits? I mean if I were hypothetically running a few appliances (TV, microwave, small A/C?) would it blow their fuses because it was running on only one of their outlets? Would they need to install some new circuits or fortify their wiring?
Also, how would I tap into their sewer system? Assuming I want a flush toilet and not a composting one, would they essentially have to build an RV "dumping station" in their back yard for me to use? Would I leave it permanently connected to that? Would I be able to just leave the graywater and blackwater tanks open in that case?
If they did build the equivalent of an RV park's "full hookup" system, what would that sort of thing cost? Again, I'm not exactly clear on how RV full hookups work... I've never stayed in an RV or at a campground that had RV hookups. I'm just interested in how everything works, not why this is a terrible idea.
