If you don't mind a short drive, why not stay where the Army's famed 10th Mountain Division trained during WW2 at Camp Hale?
Other than the NFS CG, virtually all of the valley floor around Camp Hale was closed to camping when we were there last year. Big cleanup project involving both asbestos and unexploded munitions. We haven't been by there this spring to see if the closure is still in place, so a call to the FS might be warranted.
It's a bit of a grunt out of Minturn heading south. If you do want to go that way, Hornsilver NFS CG is before you get all the way to Camp Hale. Little in the way of trees, but it is at 8700'so it doesn't get real warm. First come first served, no reservations.
Depending on what days you will be there, you might check Sylvan Lake SP. They have some spotty days open during the week in July. Again no hookups, but at 8500'.
Maybe someone else with more up to date info can chime in here, but there used to be dispersed camping on the Shrine Pass Road off the top of Vail Pass. I don't know the current conditions of the road either. But something to investigate. You'd be around 11,000' so a/c would definitely not be needed.
