I planned to park my house in a trailer park, and purposefully built my house to have the same kind of hookups as an RV or manufactured home.
For power, I installed a 50amp RV-style power inlet to my house. I ran a 50-amp cable from from the power pole to my house.
For water, I was able to connect a standard drinking-water hose from the water line to the inlet into my house.
For natural gas, I ran copper flex tubing from the gas meter to the gas inlet in my house. I ensured that all of my gas appliances had the correct orifices.
For sewer, I drained all of my water fixtures (two sinks, shower, and toilet) through the floor, connected them to a common drain line, and through a sewer hookup below the house.
