Jim,

I have driven 411 from Newport into Sevierville in a semi, and while it is narrow and curvy in spots you will be able to make it with no problems.

However, my issues with the narrow TN roads are not with my ability to stay in my lane on the narrow roads, but with the yahoos that are local, familiar with the roads, and driving their clapped out pickups too fast coming at you from the other direction. Personally I would take I 40 from either direction to exit 407 and proceed south from there to the campground. Coming from my house there is a shorter way, but I will be taking I 40 to exit 407.

The benefit to the guys using this routing is that they get to see the Bass pro shop, the Smokey Mountain Knife works, and the Tool Place next to the knofe works. That is good stuff to remember for a place to visit on the free day while the wives are at the outlets spending money.
