The Phoenix area is a wonderful wintertime snowbird retreat, but it gets hotter than a two dollar pistol in the sumertime. Assuming it will be plugged into electricity all summer, then in addition to what Bill Aders suggested, I'd do two other things.
1] Jack the rig up until there is no weight on the tires, put it on jackstands, then cover the tires so no direct sunlight can hit them.
2] Cover the entire rig with a breathable RV cover that blocks almost all the UV rays from the sun. Not cheap. The good stuff for a large TT will probably cost over $400 at Camping World - maybe less on line. But it will protect the finish from the intense summertime UV rays.
Now that's assuming you will leave the rig plugged in to electricity, so the AC and battery charger work. But if you plan to unplug the rig, then additional steps are required.
1] Turn off the empty refrigerator, clean it spic and span, then block the door(s) open.
2] Flush out the black and grey water tanks, then drain them. Drain the fresh water tank. Drain the water heater.
3] Disconnect the battery(ies). If the battery(ies) are out in the open, such as on the hitch of a TT, then move them into the "basement" storage space inside the trailer. Or better yet, take them home with you and plug them into a battery tender while you're home.
4] Crack open a roof vent and a window. The RV cover should keep dirt out, and the window and vent screens should keep the critters out.
5] If your parking place is metered for electricity so that you pay for what you use, then I'd set the AC to 90° F. instead of the 85° Bill mentioned.
What do I do? When not on the road, I keep my TT in a barn to keep that nasty ole UV off it. I plug it in only to keep the battery charged up. It doesn't get quite as hot here as it does in Phoenix, so I don't worry about running the AC when it's stored in the barn.
