Depending on the time you have, you could do as we have often done: Spend a few nights in Santa Fe (I concur with Santa Fe Skies, but we also like Ranchos de Santa Fe on the east); then move on up to Taos. We prefer Taos Valley RV Park. But last Summer we stayed up at the Taos Ski Valley for free on their parking lot. No hookups, no campfire, but access to both shops and great trails. Also great cell signal.
While you are in Santa Fe, you should take a day drive up the Old High Road to Taos, stopping in Chimayo for lunch at Ranchos de Cheymayo, one of New Mexico's great restaurants. Stop also at villages such as Truchas and Trampas and the old mission churches. You can scoot back to Santa Fe on the main highway.
We enjoy eating breakfast and/or lunch at Michael's Kitchen in Taos.
