mobile home communities are set up all over the place and each one has different amenities. some are for seniors, some take everyone, some are low income, etc. All that I know of provide water/sewer/electricity connections for each plot of land in the park - you pay utility bills just like everyone else does. One way to locate the parks is to check with a real estate agent...but they'll try to sell you one and get a commission - if you can put up with their sales pitch, you can get a lot of information. try googling "mobile home parks" in a certain location and you should get hits to check out. there is air conditioning, just like a regular house, and yes, there are parks in cold climates...they have them in Alaska. However, mobile homes may not be as energy efficient as a regular house...you have to make sure you get a well built one. Just think of a mobile home as a house in a small community...schools may be near or far depending on where the community is, some are in the middle of town, some are towns themselves...If you own your own land, you have to check the community codes to see if you can put a mobile home on it...my guess is that in a planned community or a city you may not be able to move in a mobile home, but in the country you can do it anywhere. mobile homes are homes that look different - you have to consider codes but can use them anywhere codes permit.
