Rancho Sedona RV Park is the only one actually in Sedona....nice, treed, by the creek, pricey.
Dead Horse Ranch State Park in Cottonwood would be second choice for me.
Click on "RV Parks" at the top of this website, and type in Sedona. You'll see a list of other good options in the Verde Valley. Distant Drums by the casino and I-17, Verde Ranch very new also by I-17 in Camp Verde, Rain Spirit in Clarkdale also pretty new looks nice with nice surrounding view.
