From Moab to Zion (don't know Y anyone would leave Moab area) I hope U go down Rt.24 thru Capital Reef Nat'l Pk. Fruita RV pk., 1st come 1st serve, in Cap. Reef is very nice, but water only. and than down Utah, Rt.12 (Nat;l Scenic Byway)Escalante St.Pk. pass Kodachrome, Bryce Canyon (Ruby's Inn Rv Pk) and down to North Rim. The Canyons Nat'l Pk cg is very nice, but water only. As for the Vermillion cliffs, I'd go to Page and stay at Wahweap RV resort. Wonder, full hookup, paved, large sites with great views of the lake. A very good place to go on 'Day Trips' to explore the area like the AMAZING dam & bridge & the world famous Antelope Slot canyon. From Page down Rt.98 to Rt.160 & 163 to Monument valley. All very nice hyways. Goulding is a decent place. U didn't say what U'r driving, But if any kind of a fairly high clearance vehicle, be sure to do the self guided loop road thru the spires. Buy Native Jewelry down in the valley along this road not at the extremely high priced Visitors center/store.
