I went both ways for a Short Distance, I HAVE NEVER DROVE SUCH NARROW ROADS in my Life
Try it pulling your 5'er in and around Gatlinburg.
Jim and TN, You guys seem familiar with the area. Coming into Gatlinburg on 441 (I think thats the road into town) at intersection 3 there is a campground on the corner and the road to the left is called 'Dudley Creek Bypass' to Highway 392. The road goes straight up for about a 1/4 mile, makes a 90 degree turn and straight down for about a 1/4 mile stopping on 392. Did this with a 32' fifth wheel. That was pretty intense!
Buford, Just outside Pigeon Forge I think, is a pretty cool caverns to tour. Loved it. Also downtown there is a musclecar museum that is a must see for car lovers. Also in Sevierville is the Smokey Mountain Knifeworks.
Over in Sweetwater is the Lost Sea, largest underground lake in America.
Man, I need to get the camper back on the road.....
