Hi, don't know where you looked on the web but check RVParkreviews.com
Just as an example Johnson's corner RV Retreat list rates of $400 to $450 a month plus electric, I have spent two summers there not bad but the noise from IH 25 is pretty loud if you are in the front row, and the wifi is nothing to write home about. Loveland Station list there rate at around $380 a month, nothing fancy about this park and I don't know about their wifi. As far as I know Fort Collins just has a KOA and no idea what they would charge you a month. You don't indicate where you need to be close to so keep in mind from Fort Collins you are only about 35 miles to Cheyenne Wyoming and there are a couple RV Parks there.
Good Luck
Bill
