We spent the night in Aztec, NM last October about 35 miles south of Durango, and stayed at Ruins Road RV park and campground. As I recall they had good wifi, overall a reasonably ok cheap place to spend the night, gravel sites, with reasonable spacing, on the banks of the river, but high enough above water level to not worry much about flooding, a fair number of long term tenants (people with wood decks, large propane tanks, etc.).
I recall using their wifi, but honestly am a little vague on the details, I do recall that one of their wifi antennas was on a post next to our site.
