I like Dancing Eagle Casino/RV park at exit 108 between Albuquerque and Grants NM. for an overnight stop and or tour of Sky City (Acoma Pueblo). There is a supermarket with a great deli (IMO) and the RV park
link was $10 w/full hookup, plus the casino, travel center, etc.
Santa Rosa, Tucumcarri, Grants, Gallup, and casinos all along the way in NM.
Homilovi State Prk in AZ east of Winslow is nice enough but only has dump station, there is a commercial park in Winslow that was the same price and full hookup last I checked.
