Unless there is something in Chattanooga you want to see, I would suggest staying on I-40 to NC and take Hwy 23 (Exit 27) which will be nice dual lane road to Franklin. Hwy 64 from Chattanooga is a lot of single lane curvy road to just outside of Franklin. Doable, but not enjoyable with your rig. Adds 50 miles to the trip but think it's worth it. This is based on local knowledge from having land near Sylva, NC and wheeling for years in Tellico Plains.
US-64 is very doable, many 18 wheelers travel it every day. There is a 10-mile stretch through the Ocoee gorge that is 2-lane, very curvy, and has no shoulder. But it is not as bad as it was before the 2009 rockslide.
If you don't want to do US-64, you can go 20 mile south down I-75 to Dalton GA and run US-76 to Clayton GA and north up US-23 to Franklin NC
