If you don't mind staying in a Walmart parking lot I suspect that any RV park/campground will be fine. I suggest you just follow your nose for a while - drive until you find something interesting or get tired - there are plenty of people who want to "plan" every trip and I suspect they don't realize they miss the real enjoyment of Rving. I doubt that a roadside rest stop is any worse than a Walmart parking lot.
I would also suggest that you create a list of all the Casinos all along your RV route. Most will allow you to park overnight even if they don't have a RV park.
