We are looking for places to stay in our 5th Wheel-2 seniors
Could be state parks, campgrounds, Corp of Engineer parks etc
Any suggestions of places you've stayed that you really liked? We prefer shade this time of year.
Thank you in advance!

Colorado State Parks are reservation only, there no longer is any first come/first served. You might be able to find an opening at Cherry Creek State Park on the SE side of the Denver Metro area.

Otherwise, in July, most everything is likely to be booked up, even for during the week. Possibly some openings at commercial RV parks, but they will likely also be hard to find for the Denver area.

In Cheyenne, shade will be at a premium. The good news is there's probably been lots of reservation cancellations since Cheyenne Frontier Days has been cancelled this year due to the coronavirus. Two of the better places in Cheyenne is the KOA on the east side of the city off I-80, or the Terry Bison Ranch RV Park just inside Wyoming on I-25 at the first exit.
