Formerly from West Texas, I would recommend Ruidoso NM, Calsbad Caverns, Balmorhea Springs for sightseeing and/or camping. I have stayed at Hilltop RV (Ft Stockton) a couple times for quick overnight stops. It is very decent and easy, but with caliche drives and parking areas. Be aware that the ongoing oil boom has a lot of RV parks along that route full to capacity. Most keep a few spots for overnight stays.
