Ron,
We keep an RV in Angel Fire all year. We don't ski anymore, so we don't go there during the winter. However, we visit many times each summer (live only 3 hours away). I don't know anything about the cabin shares; we have never used them. We stayed in one of the condo units several years ago that wasn't great, but I think they have been doing a lot of upgrading in the last few years.
Steve gave a good general description of the area. Angle Fire sits in the Moreno Valley and has beatuiful views of the surrounging mountains including New Mexico's highest peak Mt. Wheeler (13,160 ft.) Here are some other features: 2 indoor swimming pools (one at the lodge and one at the country club), a nice 18 hole golf course at the country club, a lot of fishing possibilities (streems and lakes), decent restaurants (one real good one called the Roasted Clove) and a lot of back roads and trails to explore.
If you like outdoor activities, you'll like AF.
