You mentioned Scottsdale which really isn't a RVers paradise. If you want the greater Phoenix area go over toward the Apache Junction area. It's a lot more pleasant than Phoenix, Scottsdale or Mesa.
Agreed with another poster above that if you're up to moving after two weeks, you can't beat the Maricopa County Parks' campgrounds. They are beauties. There's Lake Pleasant, Cave Creek, McDowell Mountain and Usery. They have huge lovely sites. Also consider Lost Dutchman State Park at Apache Junction. You won't find better scenery anywhere else in the area.
Reservations are now a must for these parks in winter as the word has gotten out that they are jewels. Good luck!
