441 from gatlinburg to Cherokee

You should be okay. Lot of elevation changes and deep curves so be rested when you do it.

This may get your attention...

It's on the uphill side going toward Cherokee, so not a real problem.

Jim, "Mo' coffee!"

But what is the height of that tunnel?

They are doing construction work on that road just inside the park, so you may want to check the NPS website for the times when it's going to be down to one lane.

Here's some info on the tunnel heights on that route

13' RV ? Must be an OutLaw Toy hauler.

The heights on the tunnels are marked and measured for the sides. Much higher out toward the center. even at 13 feet, which is darn high!!, you will be fine. Just crowd the center line and pay attention

Interesting reading here about the tunnels.
