I have a friend in Maricopa county near 101 that has a large metal building in his fenced back yard. It's open at both ends and his MH is about 15 degrees cooler than than the air. And there are various other toys in the building. He has lights, several 120V plugs 50A RV plugs with meters. Some snowbird friends stay there on and off. I bring my rig over to work on it and of course always hand him some cash not that he ever asks. Everyone has the option of using their own A/Cs.
He has a separate locked workshop with swamp cooler. All of this has evolved over the years. He ran water and has a computer which I believe is on a LAN cable to the house. In his front driveway he has a sewer drain that somehow became a RV dump. Sure not as convenient but it works well. I dumped once, moved to the back, tilted the rig away from the valves and replaced them w/o a drop spilled.
Just suggesting that you think ahead and plan what's right for you over time. Things like installing empty oonduit lines. But excellent start.
