I'm from there and if I were you I'd drive right by Chicago and wave at it as you head to Wisconsin. Nothing really there to see and your kids would be bored to tears if you took in any of the cultural sights you might like.But then again you won't be able to go downtown with your RV and there are no close by CG's. There is one in Zion on the lake but it's nothing to write home about.
Take the extra time and spend it all in Wisconsin. Endless stuff to do there, CG facilities abound and the scenery is just down right spectacular. Stay in small towns there is so much activities planned all summer especially during Dairy Month. Each town a big farm sponsors Dairy month. You get to really see how a diary farm operates and all of them have 6 foot frying pan and serve up breakfast in it! I try and make one every year. Lake Geneva, Door County good spots too.
The Wisconsin State Fair in West Allis (right outside Milwaukee) is the BEST fair of all the states. They have a full hookup CG on site. It's like no other fair you have been to. The kids will love you for the rest of your life if you take them to that! :C
As the Wizard of Oz said: "Pay no attention to that man behind the curtain. I don't know if the above comment was being serious or not, but there are incredible things to see and do in Chicago. As others have said, you can stay at McCormick place on the lake (parking lot and pricey, but very convenient). And if you have kids, they will absolutely love the Museum of Science and Industry, the Field Museum (dinosaurs and mummies), the Shedd Aquarium (dolphin shows, beluga whales), the Adler Planetarium (space!), if you bring your bikes you can bike on a paved bike trail up the entire shoreline and almost never cross a road. Just north of the Loop is Lincoln Park with a large and free Zoo. In the suburbs is Brookfield Zoo, even larger and more animals. As others have mentioned, the Art Museum (near downtown Grant Park) is great. Also near downtown is Navy Pier a fun tourist attraction that juts out into the lake. Take a boat tour. Someone mentioned Auditorium Theater - I saw The Who perform there in the early 1970's! :)
In short, there are tons of things to do right near downtown Chicago, and many are in walking distance from each other. Shedd, Field and Adler are all together at the Museum campus on the lake.
But Milwaukee and Wisconsin have great places too. But you'll be sorry if you by-pass Chicago.
