We are in the same boat...Houston heat and humidity. August 2020 we spent near Durango Colorado. It was OK but I'm looking for something more midwest or east coast. We spent a little time in Iowa and central Illinois this August. It was warm and occasionally humid but very bearable. I have experienced the biting flies in Ohio and would prefer to avoid that. I hear Michigan has the same flies.
Check out Roberts Creek Park (county) around Red Rock Lake near Pella IA. They have full hook ups. There are several COE parks around the lake. We fell in love with Pella, a well scrubbed Dutch town.
Be aware when the sprint car Knoxville Nationals are racing in Knoxville everything is full.
