Suggested route from Gainsville GA to Asheville NC

Just looking for route and road info from Gainseville area to Asheville NC but would love any camping suggestions along the way. We are a 34' Class A with tow vehicle, gas not diesel.

Is it better to unhook when driving through this section of the mountians or is state Rt 23 ok for pulling?

is there a better route to use than GA 23.

Thanks for any help you can give us.
