You're welcome, I hope it helps. I will add some info about overnight CGs during the winter, on our main route.
There is a nice year round campground in Sikeston, called Hinton RV Park. South of that it is slim pickings until the Memphis area. There is not much in the rest of Arkansas until Texarkana. We have stayed a few times in one that is okay, Arkadelphia CG. It's very near to a Cracker Barrel. I read that it is under new management, which should be a good thing because the previous afternoon guy was very unpleasant.
In Texarkana, we have stayed at Sunrise RV Park. It is good. Nice clean restrooms, pleasant clerks, etc. There is a Pilot or Flying J, and a Denny's at that exit. There is also a KOA in the area.
