The name has changed; there was an abrupt change of ownership recently.   The web page for Prospect RV Park will get you nothing, and the phone number is disconnected.

The new contact info is Applewood RV resort, 303-872-0091, web page https://rjourney.com/locations/co/wheat-ridge/applewood-rv-resort-llc

Seems from reviews to be nice; it's annoying that "Prospect RV Park" seems to have evaporated from the planet, and it took a lot of googling to find out about the name/ownership change.  It would be nice if the phone/web page had some forwarding.  (That's why just three stars; I may change that after we've stayed there.)
