Do you want to head out towards Tucson? There is a nice Escapees campground in Benson. It is a short drive from there to Tombstone. I was there in the November - many years ago, and the weather is pleasant that time of year.
If you want to go camping this summer, and don't want to camp in 100F weather, check out Flagstaff area, and higher elevations. Sedona is fairly high elevation, but check weather.com and see what it will look like next month! Next weekend will be crowded.
Because many people will like a vacation to a place like Grand Canyon with a 3 day weekend, it will be busy from now until June 5th. Then kids will get out of school and it will be busy all summer.
If you go to the North Rim, you can stay in the campground there - it should not be warm enough to need A/C, and it is dry camping. I personally would park out in the forest, and dry camp. I have a 400W solar system, and can stay 3 weeks until I run out of fresh water.
Tucson air museum is wonderful place to visit, if it is below 85F. So not this time of year. Check Saguaro Park, I don't think they have hookups, but it is a wonderful place to visit in the winter.
Have fun camping!

Money can't buy happiness but somehow it's more comfortable to cry in a
Porsche or Country Coach!
If there's a WILL, I want to be in it!
I havn't been everywhere, but it's on my list.
