We have stayed at Santa Fe Skies RV Park and Cochiti. The choice for us is the time of year (we snowbird in S. NM) and whether we need a FHU site.
All of the Forest Service campgrounds in SW Colorado honor the senior pass. A couple I can recommend are McPhee Reservoir Recreation Complex near Mesa Verde NP, Haviland Lake and Junction Creek cgs near Durango, and Cayton cg south of Telluride, all with 30/50A electric hookups, water faucets, and a dump (although McPhee's dump is closed this year).
For more info on camping along US 160 and US 550, including the cgs mentioned here, see my blog
