Basically doing that same trip this Christmas except my drive isn't that long.
Just outside Shreveport is the Duck Commander Tours. It's where they shot the Duck Dynasty show. It was a neat, quick stop. There is a gift shop and a tour of the building.
Staying at Racoon Mountain Caverns and RV park in Chattanooga. It apparently has Caverns to explore on or adjacent the property. Says it's 15 minutes from Lookout Mountain.
We chose Up The Creek RV Camp for Pigeon Forge area. Drove by it many times when we rented cabins down the road. We like the location.
