The zoning issues are usually city or county and can limit whether you can live in the RV or trailer. The county we live in in Florida only allows trailers in RV parks or on property zoned for manufactured housing. Even then they limit the type like trailer vs modular home. If it's going to be permanent and not used for travel, I would go with a trailer, park model or tiny house that does not have holding tanks to worry about. Park models usually are hooked to sewer with pvc pipe rather than flexible hoses like RVers use. It is not advisable to leave the dump valves open on an RV. The tanks and valves dry out which would cause problems. Also with park models, trailers and tiny houses you don't leave the tires on to rot.
Some park models don't require a slab. Some trailers can be set up on blocks. You can get wi-fi with Verizon Mi-Fi or other cellular carriers but it is very expensive and the plans are based on usage, not unlimited. That is if you have decent cell signal at the property. You can get satellite for TV like DISH or Directv. The utilities are expensive as the previous post states.
