What type of things do you want to see? Arizona is full of Indian Ruin parks, especially in the North Central section of the state. Those are best seen in cool weather since they are mostly in the hot desert. Of course in the far north is the North Rim of the Grand Canyon. Vermillion Cliffs and Pipe Spring NM are close. You need to look at their web page to see when they open. The are many back country drives in the area.
Further south is the South Rim which is open all year.
As for CG what type are you looking for? FHU or fewer services?
The south of the state has Saguaro NP, Chiricahua NM but that only allows smaller RV's and we couldn't find any close by commercial parks. The NF/BLM cg are also size limited. It's a interesting park tho. Ft Apache is close and well worth a quick look around especially the cemetery with fascinating headstone inscriptions. Mary Anderson aged 24 killed by Apaches and so on.
Karchner Caverns (sp?) is also down there and is said to be a great cave. Reservations for tours required. It's on our list. Tombstone a tourist site is worth a drive by and Bisbee is worth a stop too with a mine tour.
I'm just touching on all the places to see in the state there are many more. The Desert Museum in Tucson for example and Mt Lemmon.
I'll leave NM for someone else.
