I read this entire thread. I live less than 5 miles from the Union KOA. It's not a bad place. You are forgetting to check out some of the county forest preserves in the area. Some offer hookups and others just electric and such. Marengo Ridge
As for touring Chicago the only way to do it is to take the train into downtown. Weekend all you can ride passes are 8$ each. and the train line runs well out to the far suburbs. I live 8 miles from one of the towns where the train stops. I commuted to downtown from where I live for almost 10 years for work. Some train stations have free parking others charge depending on whether its a weekend or weekday. During the week ticket prices are higher but parking downtown winds up being about the same cost and lots more aggravation.
There are a couple of private campgrounds in the area but like someone said they are mostly seasonal sites. There is one south of Marengo where I have lived for 20+ years and I don't even recall the name of it. Kane county has several forest preserves that offer camping and would also have access to the metra train lines.
