In case anyone is interested and wants to know, and unless things have changed drastically in 2 months, I would stay the hell away from White's City (the rv campground) in New Mexico, just outside Carlsbad Caverns.
While it had been recently bought out by another entity, we found the electrical hookups to be seriously faulty if not dangerous (if they worked at all). You are told to hunt around for the few 50 amp sites. We found what were apparently ground/neutral problems, as well as faulty breakers (or no power to them). I did not investigate any further because I could run off the batteries (no a/c needed at the time), and because it was pitch black outside and very tight for big rigs.
Furthermore, the entrance gate (normally operated by keppad access code I think) was defunct (they did mention that). It was two-way two lane past the gate island and overgrown with vegetation that apparently was not plant but iron based because it scratched the hell out of the sides of the coach.
Maintenance was nonexistant if you ask me, but at the site we wound up on, the sewer line worked and there was water too. We stayed 2 nights.
Stay away. That is all.
