Justin,
You have a lot of good advice here. It is a rented unit and that means that you are not familiar with it. Plan the first night in you drive way - Please....
Be real. This will really be you the wife a toddler (not much walking) and a 50# sack of flour that needs feeding and changing. Those two make a motorhome a good start.
Without knowing the specifics of the older progeny, I cannot make much for suggestions. Come back with that and you may get more help with destinations.
You really need to work on planning. There are online trip planners that I know nothing about, but if you find one and start to use it, you may get a very fast lesson about your range and capability. You will really only have one driver as the other will be nanny. If you can do a 300 mile day, that would be remarkable. You will also need to take on water, dump and re-provision about every third day. That will all take time out of the driving day.
The Natchez Trace in good, better in the spring and fall when you can see past the "Tunnel of Trees". If you want to do this, get the book first. The road is 444 miles long and there are about 220 historical markers. You may not want to stop at all, just the top 40 or 50.
Blue Ridge Parkway and Skyline Drive are a scenic drive when the world is green. If it is not you coach, start at the north end and go south. The south end is a much more difficult drive.
There are downloadable guides to both. If you start there, you could save a lot of time and effort. Our kids still remember our road tips and camping. They even mention that at family gatherings decades later. One would borrow the coach, but already has too much family for it. The other's spouse is just not a good traveler and does not want to try this out.
