Orion,
You have some good advice here, but you also ask a lot of unsaid questions and as you are new, I am going with the first night in the driveway plan. This is always a good thing.
But, let's go on...
The good planners are all gone, so let's not bother with them. You can start for free at a site
Furkotwhich is a very powerful planner, but much of it's effectiveness is almost Easter Egg. The help files are good, but it will take some sitting time to even figure out how to make it work. The circle i is the help button. The thing it does not have, is a clearance filter. I hope that you have a number for this. When you get one, take a china marker and write it at the top of your TV (Tow Vehicle - it won't do much good in the entertainment center - I'll give you a moment to think about why I had to add that) windshield.
Problem with Furkot and everything else that is available today is that they are all webapps. Even if you carry wire (we do have internet access underway), it will still be limited value as data coverage outside of the eastcoast megopolis is spotty.
Now, a place to set up and camp - In Cinci? Right? Well, start by joining
FMCA (Family Motor Coach Assoc). This is not expensive and they have some good benefits. The first thing you want is the FHU (Full Hook Up- Water, Electric & Sewer) at their Round Bottom Road site. I can't think of a better place to learn about parking and setting up. I think you can pay to stay if not FMCA, but I have never not been, so I am not certain.
If you chose to do this, I suggest that you only consider accessing via Round Bottom Road. Batavia Pike will bring you straight in from exit 63, but the is a 300+ ft change in elevation that could be scary for a first time. (In a few thousand miles, it won't matter.)
There is another part of your learning curve that you have to climb every early. If you used to travel by car, an 800+ mile day is not all that bad. Riding in a truck and towing a behemoth makes this a very different situation. A 400 mile day will be a lot. There will be much greater difficulty in quick stops for fuel, food and nature.
Driving and parking will be a new experience. Speaking of parking, if you don't have two cellphone, get a pair of little radios and practice both talking and parking - not at home. Take the trailer to a vacant parking lot and take along a couple of trash cans to mark you "camp site". When you are though running them over, then take the 5er home and try it there.
At this point, I will wish you many amazing stops and many boring hours of driving. Sometimes we don't need excitement.
