If you stay in commercial campgrounds you may have a better shot at getting sites. Move during the week no on weekends. You can also look on www.woodalls.com and search for "open all year"
I-75 to I-40, stop in Sevierville TN (we like River Plantation RV Park) drive through Smoky Mt Nat Pk. Especially Cades Cove if it's open.
Connect to I-81. Stop over Ft Chiswell RV Park Max Meadows VA.
KOA, Luray VA. (Skyline Drive, Caverns) Pricey KOA but one of our favorites!
In PA, Gettysburg - Artillery Ridge Campground.
To see Hershey PA we liked the KOA in Elizabethtown.
We liked Bald Eagle State Park, Howard PA.
Near the NY border, we like Ives Run Corps of Engineers Tioga PA.
Owego NY: Hickories City Park.
