Tucked in next to the Rio Grande, Perch Dam Campground is quiet, clean, and enjoyable. The bathrooms were spotless and well maintained, as were the pit toilets in the dispersed area.  Most sites easily can fit a 35 - 40 foot rig.  There is water and electric (15, 30, 50 amp) at all reserved sites.  The only drawback, no RV dump station on site; you'll need to go to Caballo SP to dump.  Had great Verizon cell service while there.  We will return!
