Elephant Butte State Park is very nice has many places some with full hookups. It is at Elephant Butte exit before one gets to T or C. There is another state park several miles south of TorC as well. Caballo Lake State Park.
Yep! the Bosque del Apache NWR is a neat place to see. Never stayed at Birdwatchers, but would if going up there with the trailer.
Another neat place, but off I-25 to the east from San Antonio, NM is Valley of Fires BLM Rec. Area & campground. The CG is very nice many with water & electric.
