Agave Gulch/FT Bliss Summer Stays

I realize these parks are full during the winter months, but how about during the summer i.e. June. I'm looking for over night stays at FT Bliss and Davis-Monthan AFB and would like FHU spots. Anyone know if they are crowded during the summer months.

Plenty of FHU sites available at Agave Gulch in June. Be prepared for the summer heat. Possibly 100+ in June.
